Question

By what number should you multiply the first equation to solve using elimination?

–3x – 2y = 2
–9x + 3y = 24

–3
6
–9
3

Answer 1

3

Explanation:

We would be eliminating -9x from the equations.

Thus, we need to make the (-3x) into (-9x) in the first equation.

-9x ÷ -3x = 3

After that, you should be able to solve the equations:

-3x - 2y = 2

Equation 1×3: -9x - 6y = 6

-9x + 3y = 24
