What should be done to these equations in order to solve a system of equations by elimination? 1-30 + 2y = 16 2.2 + 5y =21 Multiply the first equation by 2 and the second equation by 3. Multiply the first equation by 3 and the second equations by 2. Multiply the first equation by 3. Nothing needs to be done, since they both equal have 2's and 3's for coefficients.

What should be done to these equations in order to solve a system of equations by elimination 130 2y 16 22 5y 21 Multiply the first equation by 2 and the second class=

Respuesta :

Given the system of equations:

[tex]\begin{gathered} -3x+2y=16\rightarrow(1) \\ 2x+5y=21\rightarrow(2) \end{gathered}[/tex]

As shown, the coefficients of x are {-3, 2}

To solve the system by elimination, we can eliminate (x) by multiplying the first equation by 2 and the second equation by 3

So, the answer will be the first option

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