-3x+7y=-8 = [1] 5x-11y=[2]
5[1] gives -15x + 35y = -40
3[2] gives 15x - 33y = 48
[2] + [1] gives 2y=8 therefore y=4
5x - 11(4) = 16 therefore x = 12
x=18
-17
x = -1.2, y = -3
-2 + 5 = xsame as:5 - 2 = xx = 3
(3)(14) = 84x 42 =84X x=1/2

Solve the following equation for A : 2A/3 = 8 + 4A
x=18

8s=ps=p/8
The final answer is 40.
-17
3x-1=93x=10 x=10/3
x = -1.2, y = -3
