Question

Solve the system of equations using elimination. SHOW WORK!!!!!!!!!!!!!

15q – 4r = 62
5q + 8r = 86

Answer 1

That person is correct! Good luck

Answer 2

q= 6

r= 7

work--

Multiply 1st column by -2:

-30q+8r=-124

5q+8r=86

Subtract 2nd column from the first column:

-35q= -210

Solve for q:

q=6

Subtract q=6 by any of the two equations, so:

-30q+8r=-124

-30*6+8r=-124

Solve for r:

r=7
