Question

What is the solution of y=-x+3
y=4x-2

Answer 1

Solution is (1,2)

Explanation:

y = -x + 3 Substitute -x + 3 = y into the second equation

-x + 3 = 4x - 2

-5x + 3 = -2

-5x = -3 - 2

-5x = -5

`(-5x)/(-5) = (-5)/(-5)`

x = 1

y = -x + 3; y = -1 + 3; y = 2

The solution is (x, y) = (1, 2)
