Hey there!
150 = 8x + 6y
↠ 150 = 8x + 6(9)
↠ 8x + 6(9) = 150
↠ 8x + 54 = 150
SUBTRACT 54 to BOTH SIDES
8x + 54 - 54 = 150 - 54
CANCEL out: 54 - 54 because that gives you 0
KEEP: 150 - 54 because helps solve for x
↣150 - 54 = 96↢
NEW EQUATION: 8x = 96
DIVIDE 8 to BOTH SIDES
8x/8 = 96/8
CANCEL out: 8/8 because that gives you 1
KEEP: 96/8 because that gives the value of x
96/8 = x
x = 12
Answer: x = 12
Good luck on your assignment and enjoy your day!

For every 100 dollars, the sales tax would be around 8 dollars and 4 cents. Since there is still 91 dollars you would have to add around 7 dollars and 68 cents. You would go 8 x 3 for 24 plus 7 dollars for 31 dollars and then deal with the change. 4 times 3 is 12 cents plus 68 cents for 80 cents.
The total would be 31 dollars and 80 cents.
