He spent $9.00 on the card
Division property of equality, because you have to divide 8x and 80 by 10
Answer:
x=-1
Step-by-step explanation:
x − 7 = 46 − 9(x + 7)
distribute
x-7 = 46 - 9x -63
Combine like terms
x-7 = -9x-17
Add 9x to each sid
x-7+9x = -9x+9x -17
10x-7 = -17
Add 7 to each side
10x -7+7 = -17+7
10x = -10
10x/10 = -10/10
x = -1
