Question

How many solutions does the following equation have?[6x + 12]= -18. 1) No solution 2) One solution 3) Two solutions 4) Infinitely many solutions

Answer 1

hello

to find the number of solution, we need to solve for x

$\begin{gathered} 6x+12=-18 \\ 6x=-18-12 \\ 6x=-30 \\ \text{divide both sides by 6} \\ \frac{6x}{6}=-\frac{30}{6} \\ x=-5 \end{gathered}$

the equation has only one solution
