Answer:
x=-5
Step-by-step explanation:
4(x-5)+2=x+3 As the first step says, distribute the 4 (multiply all numbers in the parentheses by 4).
4x-20+2=x-3 Combine like terms. For example, the -20 and 2 are like terms because they are both their own numbers and not attached to a variable.
4x-18=x-3 Subtract x from each side. Now, we can get x to only one side.
<u>-x -x</u>
3x-18=-3 Add 18 to both sides.
<u>+18 +18</u>
3x=-15 Divide both sides by 3.
<u>/3 /3</u>
x=-5
