Solve for x:

Step-by-step explanation:

Isolate x on one side of the equation.

(x+4)/2=7

2(x+4)/2=7*2 (First, multiply 2 from both sides.)

7*2 (Solve.)

7*2=14

x+4=14

x+4-4=14-4 (Subtract 4 from both sides.)

14-4 (Solve.)

14-4=10

x=10

Therefore, the correct answer is x=10.

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
