Answer:
Step-by-step explanation:
The equation is nor properly written. Let the equations be;
9x+2y = -8 ...... 1
9x - 3x = 7 ...... 2
Subtract 1 from 2;
(9x-9x) - (2y-(-3y)) = -8-7
0 - 5y = -15
-5y = -15
y = -15/-5
y = 3
Substitute y = 3 into 2;
From 2; 9x - 3x = 7 .
9x - 3(3) = 7
9x - 9 = 7
9x = 16
x = 16/9
Hence the solution (x, y) is (16/9, 5)
Note that the equations was assumed. The same method an be applied to similar problem.
