Set up and solve a system of equations to solve the problem. casey wants to buy a gym membership. one gym has a $150 joining fee and costs $35 per month. another gym has no joining fee and costs $60 per month. when would casey pay the same amount to be a member of either gym? how much would he pay?

what is the answer?

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
