Question

Gerald and ben shareda sum of money. Gerald took $51 more than 2/7 of the money. Ben took $30 less than gerald. What was the sum of money

Answer 1

Answer:

$168

Step-by-step explanation:

let x = total sum of money shared

Amount Gerald took = 51 + $\frac{2}{7} x$

Amount Ben took = (51 + $\frac{2}{7} x$) - 30

= 21 + $\frac{2}{7} x$

(51 + $\frac{2}{7} x$) +( $21 + \frac{2}{7}x$) = x

combine like terms

51 + 21 = x - ($\frac{2}{7} x + \frac{2}{7} x$)

72 = x - 4/7x

72 = 3/7x

divide both sides of the equation by 7/3

x = $168
