What the answer to 7(x + 1) + 3(x + 1) = -10?

7(x + 1) + 3(x + 1) = -10
7x + 7 + 3x + 3 = -10
10x + 10 = -10
10x = -20
x = -2

distribute:

7(x + 1) + 3(x + 1) = -10

7x + 7 + 3x + 3 = -10

10x + 10 = -10

10x = -20

x = -2


Check:
7(x + 1) + 3(x + 1) = -10
7((-2) + 1) + 3((-2) + 1) = -10

7(-1) + 3(-1) = -10

-7 - 3 = -10


-10 = -10

since this is true, x = -2

7(x + 1) + 3(x + 1) = -10

Use the distributive property
7x + 7 + 3x + 3 = -10

Add like terms
10x + 10 = -10

Subtract 10 from both sides
10x = -20

Divide by 10 and the answer is
x = -2

7x + 3x + 7 + 3 = - 10
10x = - 20
x = - 2

7(x + 1) + 3(x + 1) = - 10
7x + 7 + 3x + 3 = - 10
10x = - 20
x = - 2

Answer: x = - 2

Checking:
7(- 2 + 1) + 3(- 2 + 1) = - 10
7(- 1) + 3(- 1) = - 10
- 7 - 3 = - 10

7x+7 +3x+3=-10

10x+10=-10
10x+10-10=-10-10
10x=-20
x=-2

7(x + 1) + 3(x + 1) = -10
7*x + 7*1 + 3*x + 3*1 = -10
7x + 7 + 3x + 3 = -10
7x + 3x = -10 - 7 - 3
10x = -20
x = -20/10
x = -2

answer to that are x=-2

Distribute to get 7x + 7 + 3x +3 = -10
Combine like terms to get 10x+10=-10
Subtract ten from both sides to get 10x =-20
Divide both sides by 10 to get x=-2

Factor (x+1) out of the LHS to get:

(x+1)(7+3)=-10, or 10(x+1)=-10. Divide by 10 to get:

x+1=-1, so x=-2
