Question

solve for b.
-3b + -7 = 8
b =
submit

Explanation:

Step1: Add 7 to both sides

To isolate the term with \( b \), we add 7 to both sides of the equation \(-3b + (-7) = 8\). This gives us \(-3b + (-7) + 7 = 8 + 7\), which simplifies to \(-3b = 15\).

Step2: Divide by -3

Now, we divide both sides of the equation \(-3b = 15\) by \(-3\) to solve for \( b \). So, \(\frac{-3b}{-3} = \frac{15}{-3}\), which simplifies to \( b = -5 \).

Answer:

\( b = -5 \)
