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"
