Question

$$2a+b+1-a=0$$

Solve for a

$a=-\left(b+1\right)$

Solution Steps

Combine $2a$ and $-a$ to get $a$.

$$a+b+1=0$$

Subtract $b$ from both sides. Anything subtracted from zero gives its negation.

$$a+1=-b$$

Subtract $1$ from both sides.

$$a=-b-1$$

Solve for b

$b=-\left(a+1\right)$

Solution Steps

Combine $2a$ and $-a$ to get $a$.

$$a+b+1=0$$

Subtract $a$ from both sides. Anything subtracted from zero gives its negation.

$$b+1=-a$$

Subtract $1$ from both sides.

$$b=-a-1$$
