3(w+2) = 4(w-3);10 To check whether 10 is the solution of the given expression, substitute 10 for w. 3(10+2) = 4(10-3) (perform the operations in parentheses) 3*12 = 4*7 (multiply 3*12 and 4*7) 36 $\ne$ 28 The statement is false, because the values on both sides of the equation are different. Therefore, the number 10 is not the solution of the equation.
