Question

Solving Equations with Fractions

Answer 1

\[\frac{ 4 }{ 5 }x+2=22\]

Answer 2

The equation didn't come out right from my p.o.v but I could guess it was:
4/5x + 2 = 22?

Answer 3

YEA!!! what i'm confused about is if you use multiply both sideds by 4/5 or by 4/5x or subtract 2?????

Answer 4

When multiplying with fractions you only multiply both sides by the DENOMINATOR so in this case: 5, but that's not all you have to multiply EVERYTHING in the equation by 5 not just both sides like you sometimes do.

Answer 5

(5)4/5x + (5)2 = 22(5)
20/5x + 10 = 110

Now you simplify the 20/5 giving you 4, rewrite the equation:
4x + 10 = 110

Subtract both sides by 10:
4x=100
And divide by 4:
x=25
