Answer:
-3
Step-by-step explanation:
Simplifying
2x + 3 + 7x = -24
Reorder the terms:
3 + 2x + 7x = -24
Combine like terms: 2x + 7x = 9x
3 + 9x = -24
Solving
3 + 9x = -24
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3' to each side of the equation.
3 + -3 + 9x = -24 + -3
Combine like terms: 3 + -3 = 0
0 + 9x = -24 + -3
9x = -24 + -3
Combine like terms: -24 + -3 = -27
9x = -27
Divide each side by '9'.
x = -3
Simplifying
x = -3
Answer:
x = -3
Step-by-step explanation:
[tex]2x+3+7x=-24\qquad\text{combine like terms}\\\\(2x+7x)+3=-24\\\\9x+3=-24\qquad\text{subtract 3 from both sides}\\\\9x+3-3=-24-3\\\\9x=-27\qquad\text{divide both sides by 9}\\\\\dfrac{9x}{9}=\dfrac{-27}{9}\\\\x=-3[/tex]
