Write an equation in slope intercept form with a positive slope less than one and a y intercept between -10 and 10
B = hours babysitting
m = hours giving music lessons
so... whatever "b" and "m" are, their sum for that week was 18
thus
b + m = 18
now, money wise, she makes $5 for "b" and that is, she made 5*b or 5b that week
for "m", she makes $12, so for that week she made 12*m or 12m
whatever "b" and "m" are
thus
5b + 12m = 139
now

solve for "b", to see how many hours she spent babysitting
