2016年7月9日 · -13 Using the mnemonic Please Excuse My Dear Aunt Sally we are reminded that in the order of operations we follow P = Parenthesis larr brackets E = Exponents M =Multiplications D = Division A = Addition S = Subtraction To solve 3 - 3 x 6 + 2 We would do the multiplication first 3 - 18 + 2 Then we do the addition and subtraction working left to right -15 + …

2018年7月14日 · To solve for the variable x, we have to isolate it (make it by itself). To do so, first add blue6 to both sides of the equation: 3x −6 + 6 = 6 + 6 3x = 12 Now divide both sides by 3: 3x 3 = 12 3 Therefore, x = 4 Hope this helps!

2015年7月15日 · If identical standard arithmetic operations (other than division by zero) are performed on both sides of an equation, the equation remains valid. (x=1) 3x+3 = 6 color (white) ("XXXX")Subtract 3 from both sides 3x = 3 color (white) ("XXXX")Divide both sides by 3 x=1

2016年4月22日 · y = |3x +6| is the combined equation for the pair of lines y = ± (3x + 6), subject to the condition y ≥ 0. These two lines cut at (− 2,0) The V-like part of the pair of lines from and above the point of intersection (− 2,0) makes the graph.
