The sum of the ages of josh and Noelle is 118 years ,9 years ago, Joshs ages was 4 times Noelles age ,How old is josh now

if both of them were 9 years younger the sum would be 100 years combined, if josh was 4 times older then Noelle the only answer would be that josh was 80 and Noelle was 20 9 years ago, making josh 89

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
