Question 635015
3x + 4 = 19


we have to keep the variable x on one side of the equation. lets keep it on the left hand side of the equation. 4 has to be moved to the right hand side of the equation.

How do we remove the 4

add -4  on both sides

3x+4 -4 = 19-4
+4 & -4 cancel off
3x= 15

To find the value of x the co efficient of x should be 1

so we divide both sides by 3

{{{(3x/3)=(15/3)}}}

x= 5
