What is the answer to number 23
attashe74 [19]

The answer is 50/27 or 1 23/27 or approx 1.85185. Here is my work!

Multiply both sides by 10 : 20x + 6x = 50 - x

Collect the like terms: 20x + 6x = 50 - x

Move Variable to Left: 26x + x = 50

Collect like terms: 27x = 50

Divide both sides by 27: 50/27

Hope this helped :))
