Zoe paid 18.60 in sales tax and tips for dinner. The sales tax rate is 11% and she tipped 20%. ( the sales tax does not apply to the tip, and the tip is based on the price of dinner before sales tax.)

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=
