# How do you solve #3x + 16= x#?

##### 3 Answers

#### Explanation:

We can begin by subtracting

We can divide both sides by

#### Explanation:

Okay, so what you do here is isolate the variable,

Now, divide both sides by

#### Explanation:

#"collect terms in x on the left side and numeric values"#

#"on the right side of the equation"#

#"subtract x from both sides"#

#3x-x+16=cancel(x)cancel(-x)#

#rArr2x+16=0#

#"subtract 16 from both sides"#

#2xcancel(+16)cancel(-16)=0-16#

#rArr2x=-16#

#"divide both sides by 2"#

#(cancel(2) x)/cancel(2)=(-16)/2#

#rArrx=-8#

#color(blue)"As a check"# Substitute this value into the equation and if both sides are equal then it is the solution.

#(3xx-8)+16=-24+16=-8=" right side"#

#rArrx=-8" is the solution"#
