Answers
Step-by-step explanation:
1.
\begin{gathered}2x + 3 = 7 \\ 2x = 7 - 3 \\ 2x = 4 \\ x = 2\end{gathered}
2x+3=7
2x=7−3
2x=4
x=2
4.
\begin{gathered}3x + 6 = 6 \\ 3x = 0 \\ x = 0\end{gathered}
3x+6=6
3x=0
x=0
2.
\begin{gathered}3x + 2 = 23 \\ 3x = 21 \\ x = 7\end{gathered}
3x+2=23
3x=21
x=7
7.
\begin{gathered}2x + 8 = 0 \\ 2x = - 8 \\ x = - 4\end{gathered}
2x+8=0
2x=−8
x=−4
5.
\begin{gathered}4x + 5 = 17 \\ 4x = 12 \\ x = 3\end{gathered}
4x+5=17
4x=12
x=3
8.
\begin{gathered} 7x + 14 = 21 \\ 7x = 7 \\ x = 1\end{gathered}

7x=7
x=1
3.
\begin{gathered}5x + 12 = 53 \\ 5x = 41 \\ x = \frac{41}{5} \end{gathered}
5x+12=53
5x=41
x=
5
41
6.
\begin{gathered}6x + 7 = 25 \\ 6x = 18 \\ x = 3\end{gathered}
6x+7=25
6x=18
x=3
9.
\begin{gathered}8x + 24 = 40 \\ 8x = 16 \\ x = 2\end{gathered}
