Question

What is the value of x in the equation 0.5x+3=4.5?

Answer 1

x = 3

Explanation:

Collect like terms

0.5x = 4.5 - 3

0.5x = 1.5

Divide both sides by 0.5

0.5x/0.5 = 1.5/0.5

x = 3

Using fractions,

1/2x = 9/2 - 3

1/2x = 3/2

Divide both sides by 1/2

x = 3/2÷1/2

Reciprocate

x = 3/2 × 2/1

x = 6/2

x = 3

Answer 2

x=3

.5(3)= 1.5
1.5+3=4.5
