Question

What is the solution

-3x + y = 2

y = x + 4

Answer 1

to find the solution, we substitute y = x + 4 into the other equation.

-3x + (x + 4) = 2

-3x + x + 4 = 2

-2x = 2 - 4

-2x = -2

x = 1

to find y, we substitute x to the x variable in the y equation.

y = 1 + 4

y = 5

therefore, when combined, it is (1,5).
