2016年8月15日 · x= 3 or x = -2 All the numbers in the equation are even, so divide through by 2. x^2 - x - 6 = 0" find factors" The factors of 6 which subtract to make 1 are 2 and 2.

2018年6月23日 · See a solution process below: First, group and combine like terms on the left side of the equation: 2x + 12 - 7x = -2 2x - 7x + 12 = -2 (2 - 7)x + 12 = -2 -5x + 12 = -2 Next, subtract color(red)(12) from each side of the equation to isolate the x term while keeping the equation balanced: -5x + 12 - color(red)(12) = -2 - color(red)(12) -5x + 0 = -14 -5x = -14 Now, …

2018年3月3日 · x = 7, -2 |2x - 5| + 3 = 12 Given Equation |2x - 5| = 9 Subtracted 3 from both sides |2x| = 14 Added 5 to each side. x = 7 Divided 2 by both sides Since this is absolute value, you are also required to also solve the equation where in this case x could also be negative aswell as positive. -|2x - 5| + 3 = 12 -2x + 5 + 3 = 12 Distributed the negative sign. -2x + 8 = 12 Added 5 …

2018年2月27日 · Setting the equations equal to each other, we find x=-2. and y is given as y=-8 Each equation has the subject as 'y', so we can say: y = y :.-8=y=-2x-12 This is the same as: -8=-2x-12 Next, we solve for x: 12-8=-2x-12+12 4=-2x 4/-2=(-2x)/-2 -2=x

2012年11月5日 · 1/2x=12. 1. Eliminate the fraction by multiplying both sides by the reciprocal of 1/2 which is 2. 2(1/2)x = 12(2) In this equation x= 24. In this equation, eliminating the fraction also solved the equation. _____ Let's do another example to demonstrate all 3 …

2015年9月11日 · The slope is -2/3. Convert the given equation to the slope-intercept form by solving for y. 2x+3y=12 is the standard form for a linear equation. To determine the slope, solve the equation for y in order to convert to the slope-intercept form y=mx+b, where m is the slope and b is the y-intercept. 2x+3y=12 Subtract 2x from both sides. 3y=-2x+12 Divide both sides …

2017年5月31日 · It's all the space under the straight line y=-2/3x+4 you can write the inequality as 3y<=12-2xrarry<=-2/3x+4. Now you are looking for the y values that are under the line y=-2/3x+4 so all the space under the blue line in the graph graph{-2/3x+4 [-10, 10, -5, 5

2017年11月7日 · D_y= {x inRR:x>6}, R_y=RR On the real plane, we know that lnu is only defined for u>0. So letting u=2x-12, ln(2x-12) is only defined for 2x-12>0 rArrx>6. We also know that the range of any lnu is always the real numbers. thereforeD_y= {x inRR:x>6}, R_y=RR
