Brian mix 8 cups of milk to make 6 dozen brownies at that rate how many cups of milk would he need to make 15 dozen brownies
15 / 6 = 5/2
8 * 5/2 = 20
infinite many solutions
when the expressions are simplified, the variables will disappear and a true statement like -25=-25 or 0=0 is left. this means that there are an infinite many of solutions to solve the equation.
any number substitute for x will satisfy the equation.
