Question

Find the solution of the system of equations.
- 7x – 9y = -94
-2x – 9y = -59​

Answer 1

x = 7

y = 5

Explanation:

Solve for x in −7x−9y=−94

x = − 9y - 94/ 7

Substitute x = - 9y-94/7 into -2x - 99 = -59

2(9y-94)/7 - 9y=-59

solve for y in 2(9y-94)/7 - 9y = -59

y = 5

substitute y = 5 into x = - 9y-94/7

x = 7

Therefore

x = 7

y = 5
