One Step Adding Equations

18+m=8

• m=0

• m=10

• m=-10

• m=8

Which equation fits ?

The sum of a number and 6 is 28.3

• x + 6 = 28.3

• x = 6 + 28.3

• x + 28.3 = 6

• x - 6 = 28.3

solve for x

x + a = b

• x = b - a

• x = a - b

• x = a + b

• x + a = b

Solve for x

x - p = h

• x = h + p

• x = h - p

• x = p - h

• x - p = h

which equation matches?

16 more than a number is 84

• x + 16 = 84

• x - 16 = 84

• x = 84 + 16

• 16 - x = 84

Which equation matches? My mom gave me $2.50 to add to my coin collection and now I have $8.95

• x + 2.50 = 8.95

• x - 2.50 = 8.95

• x = 2.50 + 8.95

• x = 2.50 - 8.95

What is the correct step to solve for the variable?
15 = m - 5

• add 15 to both sides

• add 5 to both sides

• subtract 15 from both sides

• subtract 5 from both sides

x+8 = 15

• 5

• 6

• 7

• 8

x+22=53

• 21

• 31

• 75

• 80

x + 40 = 120

• 90

• 80

• 70

• 81
