What you do is multiply each number by 35. You get 35 by multiplying the denominators, 7 and 5. You then multiply the numerators and 51 by 35. Once you multiply the numerators you divide that answer by the denominator. Just remember, you multiply all of the numbers by 35 in this equation and ONLY divide the the answer by the denominator if it’s in a fraction.
When you convert them all..
10x+7=51
Now you can isolate the variable.
Subtract both sides by 7 so then it looks like..
10x = 24
Divide both sides by 10
Answer: x = 2 4/10; simplified to 2 2/5
