Answer:
x = 5
Step-by-step explanation:
3x + 1 = 16
Subtracting 1 on both sides of the equation,
3x + 1 – 1 = 16 – 1
Summing algebraically (in this case subtracting by having different signs) on both sides,
3x = 15
Isolating x by dividing both sides by 3
3x / 3 = 15 / 3
Dividing,
x = 5
Answer:
[tex]x=5[/tex]
Step-by-step explanation:
We have the following expression:
[tex]3x+1=16[/tex]
and we need to solve for [tex]x[/tex], so the first thing we have to do (in order to leave the x alone on one side of the equation) is move the +1 to the left sife with the opposite sign (-1):
[tex]3x=16-1\\3x=15[/tex]
now we divide each side by 3, and we get:
[tex]\frac{3x}{3}=\frac{15}{3} \\x=5[/tex]
the answer is [tex]x=5[/tex]
