Question

Slove the equation3 (c + 5) - 7 = 23

Answer 1

Given the following equation:

`3(c+5)-7=23​`

Step 1. You must apply the Distributive property:

`\begin{gathered} (3)(c)+(3)(5)-7=23​ \\ 3c+15-7=23 \end{gathered}`

Step 2. Solve the subtraction:

`3c+8=23`

Step 3. Apply the Subtraction property of equality by subtracting 8 from both sides of the equation:

`\begin{gathered} 3c+8-(8)=23-(8) \\ 3c=15 \end{gathered}`

Step 4. Apply the Division property of equality by dividing both sides of the equation by 3:

`(3c)/(3)=(15)/(3)`

The solution is:

`c=5`
