3x + 1 = 8
move +1 to the other side
sign changes from +1 to -1
3x+1-1= 8-1
3x= 7-1
divide by 3 for both sides to get x by itself
3x/3= 7/3
Answer:
x= 7/3 and x= 2 1/3
Answer:
[tex]\large\boxed{x=\dfrac{7}{3}=2\dfrac{1}{3}}[/tex]
Step-by-step explanation:
[tex]3x+1=8\qquad\text{subtract 1 from both sides}\\\\3x+1-1=8-1\\\\3x=7\qquad\text{divide both sides by 3}\\\\\dfrac{3x}{3}=\dfrac{7}{3}\\\\x=\dfrac{7}{3}[/tex]
