Answer:
The answer is negative five or -5.
Step-by-step explanation:
First, you need to distribute your equation and at the end, the -4 should be just 2x - 8.
Second, subtract the numbers 4 and -8, which will equal to -4.
Third, rearrange your terms. Those terms would be -4 + 2x, so it should be 2x - 4.
Fourth, distribute again but with -7(x + 7) and you should get -7x - 49.
Fifth, add four to both sides of your equation. It should be like 2x - 4 + 4 = -7x - 49 + 4.
Sixth, add the numbers for the both sides. Therefore, you have 2x = -7x - 45.
Seventh, add 7x to both sides of the equation. You add it to 2x and -7x - 45 + 7x.
Eighth, simplify by combining like terms which you get 9x = -45.
Ninth, divide both of the sides of your equation by the same term. Your number to use when diving is 9.
Tenth, simplify but cancel terms that are both the numerator and denominator. Then you divide the numbers and get -5.
