Answer:
1.) 7
2.)8
3.)3x
Explanation:
1.) adding 7 makes the solution false meaning that there are no solutions.
2.) adding 8 makes the solution true meaning that all solutions for x will work when plugged in
3.)Subtract 3x from both sides
Subtract 8 from both sides of the equation (-3x = -8)
Multiply both sides of the equation by (-1) : 3x = 8
Divide both sides of the equation by 3
x = 8/3 or 2.667
