Osted a new question: Solve: 3x+1= 7​

Answer 1

Answer:

$x=2$

Step-by-step explanation:

$3x+1= 7$

$3x = 6$             Subtract both sides by 1.

$\frac{3x}{3} = \frac{6}{3}$             Divide both sides by the coefficient.

$x = 2$

Check your work:

$3x+1=7 \\ 3(2)+1=7$      

$6+1=7\\7=7$        

$x=2$
