Question

3*(x+1)-2*(x-1)=-(x+5)
pfvr

Answer 1

O valor de "x" é igual a - 5.

Explicação passo-a-passo:

$3(x + 1) - 2(x -1) = - (x + 5)$

$3x + 3 - 2x + 2 = - x - 5$

$x + x + 5= - 5$

$2x = - 5 - 5$

$2x = - 10$

$x = \frac{ - 10}{2}$

$\boxed{\red{x = - 5}}$

Answer 2

Explicação passo-a-passo:

3(x+1)−2(x−1)=−(x+5)

1 Remove parentheses.

3(x+1)-2(x-1)=-x-5

3(x+1)−2(x−1)=−x−5

2 Expand.

3x+3-2x+2=-x-5

3x+3−2x+2=−x−5

3 Simplify 3x+3-2x+23x+3−2x+2 to x+5x+5.

x+5=-x-5

x+5=−x−5

4 Add xx to both sides.

x+5+x=-5

x+5+x=−5

5 Simplify x+5+xx+5+x to 2x+52x+5.

2x+5=-5

2x+5=−5

6 Subtract 55 from both sides.

2x=-5-5

2x=−5−5

7 Simplify -5-5−5−5 to -10−10.

2x=-10

2x=−10

8 Divide both sides by 22.

x=-\frac{10}{2}

x=−
