Answer:
18x + 48 = 20
Step-by-step explanation:
Rewrite the equation below so that it does not have fractions. 3/4x+2=5/6 do not use decimals in your answer.
We are given the expression:
3/4x + 2=5/6
= 3x/4 + 2 = 5/6
Rewriting the Equation so that it does not have fraction is, we Multiply both sides by the 24
= 3x/4 × 24 + 2 × 24 = 5/6 × 24
= 3x/4 × 24 + 48 = 5 × 4
= 3x × 6 + 48 = 20
= 18x + 48 = 20
Therefore, the Equation without fractions = 18x + 48 = 20
