Question

What is the souloution to the systems of equetions y= -2x - 6 and 2y = 4x - 12

Answer 1

x = 0, y = -6

Explanation:

Given the equations;

y= -2x - 6.... 1

2y = 4x - 12 ... 2

Substitute equation 1 into 2;

2(-2x-6) = 4x - 12

-4x -12 = 4x -12

-4x - 4x = -12+12

-8x = 0

x = 0

Substitute x = 0 into 1;

From 1;

y= -2x - 6

y= -2(0) - 6

y = -6

Hence the solution to the system of equations is (0, -6)
