Question

Solve the system of equations y = 2x - 5; y = -2x + 3

Answer 1

Solving gives us the result, x = 2, y = -1

Explanation:

The system of equations is,

y = 2x-5

y=-2x+3

equating the two equations, we get,

(since y = y)

`2x-5 = -2x + 3\\4x -5 = 3\\4x = 3+5\\4x=8\\x=8/4\\x=2`

and then since y = 2x-5

`y=2(2)-5\\y=-1`

so, x =2, y = -1
