Total questions = Correct Answers + Incorrect Answers
Total questions = 76/4 + 10
Total questions = 19 + 10
Total questions = 29
29 Steps: 76/4 + 10 (the questions he got right) = 19 + 10 = 29
Equation = 76/4 + 10 = q
Solve for x. a. 2 − 4 = −20
x=-8 You would move the constant to the right, calculate, then divide both sides to get x.
Solve for x. 1 3 + 5 = 14
x=9/13 You would move the constant to the right, calculate, then divide both sides to get x.
Solve for +7/3 = 4
x=5/3 You would move the constant to the right and calculate.
Solution= You would put a number bigger than 20 in the x part and see what number fits correctly/best in the x spot.
4 − 3/ 4 + 3 /4 = 9 + 3 /4
x=39/16 Cancel equal terms, move the constant to the right, calculate, and divide both sides.
. The product of a three and a number plus five is 20.

1.50(35) + 0.50(52) = 78.50
52.50 + 26 = 78.50
x + y = 87
35 + 52 = 87
