Sandy works at a clothing store. she makes $7 per hour plus earns 10% commission on her sales. she worked 78 hours over the last two weeks and had a total of $2,105 in sales before taxes.

-2

7 - 9 = -2

reversed:

-2 + 9 = 7

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
