Distribution first
2(7 + 3f) = 8 + 3f
14 + 6f = 8 + 3f
then get variable to one side
by adding -3f to both sides
14 + 3f = 8
now isolate the variable, first by addition
add -14 to both sides
3f = -6
then divide both sides by 3
f = -2

First distribute the 2 to the terms in the parenthesis.
2(7+3f) = 14+6f
14 +6f = 8 +3f
subtract 3f on both sides.
14 +6f -3f = 8 +3f -3f
subtract 14 on both sides to isolate 3f.
14 + 3f = 8
14 -14 + 3f = 8 -14
3f= -6
divide both sides by 3 to have f equal the number.
3f/3 = -6/3
f= -2

2(7+3f) = 8+3f <=>
2*7+2*3f = 8+3f <=>
14+6f = 8+3f <=>
14-8 = 3f-6f <=>
6 = -3f <=>
f = 6 / (-3) <=>
f = -2

14 + 6f = 8 + 3f
6f - 3f = 8 - 14
3f = - 6
f = - 2
