Subject: i need help ok 8w15=3w10, 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.
This gives: Therefore, w = 1 (divide both sides by 5) Check in the original equation: right side = 3w10 = 3(1)10=7 left and right side are the same so w=1 is correct
