Question

Solve each equation. Check your solution.

$3t+7=-8$

Step-by-Step Solution

Answer

The solution of the given equation $t=-5$.

Step 1. Isolate the variable.

$\begin{array}{l}3t+7=-8\\ 3t=-8-7\\ 3t=-15\end{array}$

Step 2. Solve for the variable.

$\begin{array}{l}3t=-15\\ t=-\frac{15}{3}\\ t=-5\end{array}$

Step 3. Check the solution by putting the value of t into the given equation.

$\begin{array}{l}3(-5)+7=-8\\ -15+7=-8\\ -8=-8\end{array}$
