Question

Steps to perform perform to the system of equations below so that the equations have equal x - coefficients: 4x+2y = 4 and 12x + y = 22

Answer 1

4x + 2y =4 (1)
12x + y =22 x2 -> 24x + 2y= 44 (2)
2
(2) - (1) => 20x = 40
x=2

Answer 2

• 
  `\bold{Isolate \ x \ for \ 4x+2y=4: \ x=(2-y)/(2)}`

`\bold{For \ x \ = \ (2-y)/(2)}`

`\bold{Substitute \ y \ = \ -2}`

`\bold{x=(2-\left(-2\right))/(2)}`

•
