Shelby is 7 times as old as Bonnie. If in 5 years, the sum of Bonnie and Shelby's age is 98, find Bonnies present age. use an algebraic approch
Let Bonnie's current age = x.....and Shelby's = 7x
And in 5 years, we have
[ x + 5 ] + [ 7x + 5 ] = 98 simplify
8x + 10 = 98 subtract 10 from both sides
8x = 88 divide both sides by 8
x = 11 = Bonnie's current age
yay i got that too
