Solving Word Problems That Have Decimals

Question

0.25x+0.2(x+6)=3

Answer 1

0.25x + 0.2(x + 6) = 3

Use distribution rule to elim parentheses.

0.25x + 0.2x + 1.2 = 3

Combine like terms: 0.45x + 1.2 = 3

Subtract 1.2 from both sides: 0.45x = 1.8

Divide both sides by 0.45: x = 4

Check: 0.25(4) +0.2(4 + 6) → 1 + 2 = 3
