Answer:
x = 3
Step-by-step explanation:
3(x + 2) = 6(x - 1) + 3
Divide both sides by 3.
x + 2 = 2(x - 1) + 1
Distribute the 2 on the right side.
x + 2 = 2x - 2 + 1
Combine like terms on the right side.
x + 2 = 2x - 1
Add 1 to both sides. Subtract x from both sides.
3 = x
x = 3
X + 8x = 81
9x = 81, x = 9
y = 8(9), y = 72
Solution: (9, 72)
The answer is the A. I hope this helps!
$10 / 8 = 1.25
Soo...
$6 x 1.25 = 7.50
One may note, you never quite asked anything per se, ahemm, if you meant simplification.
