Question

For each of the following systems of equations, decide whether it would be more straightforward to solve the system by substitution or elimination and indicate why. 5x 12y = -47

-2x+12y = 16​

Answer 1

Adding or subtracting (depending on the missing sign) will eliminate the y term and make it easy to solve for x

Explanation:

The first equation is missing a + or - sign

Regardless, it is easier to solve using elimination since the y coefficients are the same.
