3+7(6+2x)=157

We move all the characters to the left:

3+7(6+2x)-(157)=0

We add all the numbers and all the variables.

7(2x+6)+3-157=0

We add all the numbers and all the variables.

7(2x+6)-154=0

Multiply

14x+42-154=0

We add all the numbers and all the variables.

14x-112=0

We move all terms containing x to the left side, all other terms to the right side

14x=112

x=112/14

x=8
