ok 8w-15=3w-10, w =?????Hi,
We need to get all the terms with 'w' on one side of the equation, and all the terms without a 'w' on the other side. To that end, add 15 to both sides of the equation and subtract 3w from both sides of the equation.
Therefore, w = 1 (divide both sides by 5)
Check in the original equation:
right side = 3w-10 = 3(1)-10=-7
left and right side are the same so w=1 is correct
