Explanation:
In order to solve this linear equation, we need to group all the variable terms on one side, and all the constant terms on one side, and all the constants on the other side of the equation.
In the example: 7w-6=3w+18
Term -6 will be moved right.
Term 3w will be moved left.
Notice that a term changes sign when it moves from one side to another side of the equation.
(7w - 6) + (6 - 3w) = (3w + 18) + (6 - 3w)
Simple numerical terms (6 - 3w) are commonly written last (-3w + 6)
Therefore, your answer is 6.
W = 6
