Dec 13, 2024 · Question 1 Solve the following pairs of equations by reducing them to a pair of linear equations: (iii) 4/𝑥 + 3y = 14 3/𝑥 – 4y = 23 4/𝑥 + 3y = 14 3/𝑥 – 4y = 23 So, our equations become 4u + 3y = 14 3u – 4y = 23 Now, our equations are 4u + 3y = 14 …(3) 3u – 4y = 23 …(4) From (3) 4u + 3y = 14 4u = 14 – 3y u = (14 − ...

`a(x + y) – b (x – y) = a^2 + ab + b^2` Form the pair of linear equations in the following problems and find their solutions (if they exist) by any algebraic method: A fraction becomes `1/3` when 1 is subtracted from the numerator and it becomes `1/4` when 8 is added to its denominator.

3x-3y=4 Geometric figure: Straight Line Slope = 1 x-intercept = 4/3 = 1.33333 y-intercept = 4/-3 = -1.33333 Rearrange: Rearrange the equation by subtracting what is to the right of the ...

4x-4y=16 Geometric figure: Straight Line Slope = 1 x-intercept = 4/1 = 4.00000 y-intercept = 4/-1 = -4.00000 Rearrange: Rearrange the equation by subtracting what is to the right of ... How do you solve using elimination of \displaystyle{4}{x}-{5}{y}=-{1} and \displaystyle{2}{x}+{y}={5} ?
