Answer:
x=1/4
Step-by-step explanation:
4x+5=4+2
4x+5=6 simplify
4x+5-5=6-5 subtract from both sides
4x=1 simplify
(4x/4)=1/4 divide both sides
x=1/4 final answer
So the left side has a common denominator of 3. The 6x, -2x, and 8 can all go over a single 3. (6x-2x+8/3). Simplify the x's to get 4x. Now both sides have to be multiplied by 3 to get rid of that fraction. Then you just have 4x+8=24. Subtract 8 from both sides to get the x's alone, then divide both sides by 4 to get x alone. I have a picture to help.
