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"#
