How many solutions does the following equation have?

Question

3(x+5) = -4x + 8

Answer 1

To solve the equation, first distribute the 3 to the terms inside the parentheses:

3x + 15 = -4x + 8

Combine like terms by adding 4x to both sides:

7x + 15 = 8

Then, subtract 15 from both sides:

7x = -7

Finally, divide both sides by 7:

x = -1

So, the equation has one solution: x = -1.
