Question

Solve for x
-5(-2-5)-x-1=-12

Answer 1

Answer:

46

Step-by-step explanation:

-5(-2-5)-x-1=-12

-5(-7)-x-1=- 12

35 - x - 1 = -12

34 - x = -12

-x = -12 - (-34)

-x = - 46

x = 46

Answer 2

Answer:

$x=46$

Step-by-step explanation:

$-5\left(-2-5\right)-x-1=-12$

⟹ Subtract -2 and 5 = -7

• $5\left(-2-5\right)$

• $5\left(-7\right)$

⟹ Remover parentheses:

• $5\times7$

• $-35$

$-\left(-35\right)-x-1=-12$

⟹ Apply rule: $-\left(-a\right)=a$

$35-x-1=-12$

⟹ Combine like terms:

• $-x+35-1=-12$

• $\:35-1=34$

• $-x+34=-12$

⟹ Subtract 34 from both sides:

• $-x+34-34=-12-34$

• $-x=-46$

⟹ Divide both sides by -1:

• $\frac{-x}{-1}=\frac{-46}{-1}$

• $x=46$
