Question

For this linear equation, give the number by which you would multiply the terms in each equation in order to eliminate one of the variables. Then solve this system:
5x+2y=-1; 3x+7y=11

This would be a big help if you also include the process to help me understand the answer!

Answer 1

Answer:

Step-by-step explanation:

If we choose to eliminate x, multiply the first equation by -3:  -15x - 6y = 3

and multiply the second by 5:  -15x - 35y = 55

Note that this allows us to eliminate x.  We get:

-6y = 3

-35y = 55

which sum up to -41y = 58.  Thus, y = -58/4.

Answer 2

Answer:

Step-by-step explanation:

The solution to this system of linear equations 3x – 2y = 14 and 5x + y = 32 is (x, y) is (6, 2).
