Match each statement with the algebra expression that models it. A. The price of a winter coat and a 20% discount. ?x + 0.02x = 1.02x
B. The base salary of an employee and a 2% salary increase. ?x - 0.20x=0.80x
C. The cost of groceries and a 2% discount with coupons. ?x + 0.20x = 1.20x
D. The number of students attending school last year and a 20% increase from last year. ?x - 0.02x = 0.98x
(I think finding what the '?' marks are, please help and thank you :).)​

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

)=3(6x−9)−8

7x+(8)(x)+(8)(

4

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
