You can put this solution on YOUR website! x+3(x)=17
Multiply 3 by each term inside the parentheses.
x+3x=17
Since x and 3x are like terms, add 3x to x to get 4x.
4x=17
Divide each term in the equation by 4.
(4x)/(4)=(17)/(4)
Simplify the left-hand side of the equation by canceling the common factors.
x=(17)/(4) or 4.25 (first number)
4.25*3=12.75 (second number
Proof
12.74+4.25=17
