maria and tim sold candy bars for a fundraiser. maria sold 7 less than twice the number of candy bars that tim sold. in total maria and tim sold 137 candy bars. how many candy bars were sold by each?

Answer 1

M = 2T -7

M + T = 137

Substitute 2T-7 for M in the second equation and solve for T. Insert that value into the first equation to solve for M. Check by putting both values into the second equation.
