It would be -15 as the answer
3x + 1 + 5x = 7 + 15 + 7x
8x + 1 = 22 + 7x
x = 21
T = state income return (without sales tax)
106% of t = 4960.80
AKA
1.06t = 4960.80 --> Divide both sides by 1.06 to find the state income return without sales tax
t = 4680
Subtract t from the state income return with sales tax.
4960.80 - 4680 = 160.80
<u>She paid $160.80 in sales tax.</u>
Answer:3/2
3x3-2x2-7x+6=x+1(Multiply the numbers)
9-4-7x+6=x-1(Calculate)
11-7x=x-1(Move the terms)
-7x-x=-1-11(Collect like terms&calculate)
-8x=-12(Divide both sides by -8)
x=3/2
