(A) 8.85
(B)10.00
i think is the answer
hope i helped :)
The answer will be 10 because you plug in y=-×+12 in the equation 4x-2y=36. After you solve and do distributive property your new equation should be 4x+2x-24=36, then you add the like terms of 4x and 2x which will equal to 6x and your new equation should be 6x-24=36. Add 24 from both sides and your equation should be 6x=60, then you divide 60 by 6 and your final answer will be x=10 or 10
This simplifies to b=-6
-45 -28 + 13 = 10b
b = -60/10 = -6
