Jeff, gene, and mike need to eat an entire cake before it goes bad. The cake is cut into 8 pieces. Jeff could eat 6 pieces of cake in 2 hours, gene can eat 2 pieces of cake in 30 minutes and mike can eat 4 pieces of cake in 48 minutes. How long would it take all three to eat the cake?

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

=

10

x=5
