3(x+4)=7x
Solving linear equations

x = 3

Step-by-step explanation:

To solve this equation, we can use basic algebraic techniques as illustrated.

3(x + 4) = 7x Distribute the 3.

3x + 12 = 7x Subtract 3x from both sides of the equation.

12 = 4x Rearrange the equation so the variables are on the left.

4x = 12 Divide by 4 on both sides of the equation.

x = 3

answer: 12

step-by-step explanation:

because yes

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.
