Question

Solve the following system of linear equationy=4x - 7y=-2x + 5

Answer 1

x =6

Step-by-step explanation:

To solve the system for x, substitute the value of y from the second equation into the first to get

`2x+5=4x-7`

adding 7 to both sides gives

`2x+12=4x`

Subtracting 2x from both sides gives

`12=2x`

dividing both sides by 2 gives

`x=6`

which is our answer!
