One Step Equations with Adding and Subtracting Decimals

t + 3.924 = 15.58

• 54.82

• 19.504

• 11.656

• 5.482

When solving the equation
34.5 = p - 3, the first thing to do is to 

• add 3 to both sides

• add 34.5 to both sides

• subtract 3 from both sides

• subtract 34.5 from both sides

Solve the equation:
x - 5.5 = 10.5

• x = 15

• x = 14

• x = 16

• x = 15.5

4.9 = x + 1.5

• 4.2 = x

• 6.4 = x

• 3.4 = x

• 5.8 = x

y - 4.6 = 12

• 16.6

• 5.8

• 7.4
