Answer 4

@heyyygirrrl you got this?

Answer 5

it is actually not that easy

Answer 6

here is an easier way
put jack's age as \(x\) and since the total is 45 jill's age must be \(45-x\)

Answer 7

jack's age next year will be \(x+1\) and twice jills age last year will be \(2(44-x)\)

Answer 8

solve
\[x+1=2(44-x)\] in a couple steps
\[x+1=88-2x\]
\[3x+1=88\]
\[3x=87\] and finally divide by \(3\)
