Question

Which is the solution to the equation 0.5 x + 4.2 = 5.9? Round to the nearest tenth if necessary. 0.9 3.4 5.1 20.2

Answer 1

Answer: x=3.4

Explanation:

`0.5x+4.2=5.9`

multiply both sides by 10

`5x+42=59`

subtract 42 on both sides

`5x=17`

divide 5 on both sides

`x=(17)/(5)` or

Simplify

x= 3.4

Answer 2

x = 3.4

Explanation:

Step 1: Isolate x

0.5x = 1.7

Step 2: Divide both sides by 0.5

x = 3.4

And we have our final answer!
