Find the solution of this system of equations
8x - 5y = -8
-7x - 5y = 82

x=-6, y=-8. (-6, -8).

Step-by-step explanation:

8x-5y=-8

-7x-5y=82

-(8x-5y)=-(-8)

-7x-5y=82

-8x+5y=8

-7x-5y=82

-15x=90

x=90/-15

x=-6

8(-6)-5y=-8

-48-5y=-8

5y=-48-(-8)

5y=-48+8

5y=-40

y=-40/5

y=-8

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !
