Given the equation 5 + x - 12 = x - 7.

part a. solve the equation 5 + x - 12 = x - 7. in your final answer, be sure to state the solution and include all of your work.

part b. use the values x = -4, 0, 5 to prove your solution to the equation 5 + x - 12 = x - 7. in your final answer, include all of your calculations.

show me your step by steps to get the answers so i can do it too with the rest of the questions, i really need to know how to do this.

Part A:

Equation → 5 + x - 12 = x - 7

Combine Like Terms → -7 + x = x - 7

Subtract x to both sides → -7 + x - x = x - x - 7

Simplify → -7 = -7

Add 7 to both sides → -7 + 7 = -7 + 7

Simplify → 0 = 0

All real number are solutions.

Part B.

Using -4 for x.

5 + x - 12 = x - 7

5 + (-4) - 12 = -4 - 7

-11 = -11

Using 0 for x.

5 + x - 12 = x - 7

5 + 0 - 12 = 0 - 7

5 - 12 = -7

-7 = -7

Using 5 for x.

5 + x - 12 = x - 7

5 + 5 - 12 = 5 - 7

-2 = -2

Using all these numbers show that my original statement of "All real numbers are solutions" is correct.

Best of Luck!

what

answer: h=5.6 i don't really know how to put into words, so i though i would let you do that. i hope i was able to some

step-by-step explanation:

18 = 6(h)+1/2

18 = 6h+1/2

18-1 = 6h/2

17 = 3h

17/3 = h

h = 5.6
