Question

What should be done to these equations in order to solve a system of equations by elimination?

I- 3x + 2y = 16
12x + 5y = 21
Choose one correct answer:

Multiply the first equation by 2 and the second equation by 3.

Multiply the first equation by 3.

O Nothing needs to be done, since they both equal have 2's and 3's for coefficients.

O Multiply the first equation by
3 and the second equations by 2​

Answer 1
