Jill wants to solve the following system using the elimination method:

Question

y = x + 8
y = 3x − 11

What number should the equation y = x + 8 be multiplied by to eliminate x? (4 points)

−1

−2

−3

3

Answer 1

To eliminate x, we need to multiply the equation y = x + 8 by the coefficient of x in the second equation, which is 3.

Therefore, the equation y = x + 8 should be multiplied by 3.

Answer: 3
