Question

Y= 2x + 7 y= -4x - 5 What is the solution for the system of equations?

Answer 1

x = -2, y = 3.

as an ordered pair it is (-2, 3).

Explanation:

y= 2x + 7

y= -4x - 5

As both right hand expression are = y we have:

2x + 7 = -4x - 5

6x = -12

x = -2

Substitute for x in equation 1:

y = 2(-2) + 7 = 3.
