Key Skills Solve 3(x - 4) = 48 Use the distributive property. 3 * x + 3 * -4 = 48 3 (x - 4) = 48 Multiply 3x - 12 = 48 Add both sides of the = sign. +12 +12 3x = 60 Divide both sides of the = sign by 3. 3 3 x = 20

Key Skills Solve 5(x +2) = 35 Use the distributive property. 5 * x + 5 * 2 = 35 Solve 5 (x +2) = 35 Multiply 5x + 10 = 35 Subtract 10 from both sides of the = sign. -10 -10 5x = 25 Divide both sides of the = sign by 3 . 5 5 x = 5 TRY THIS

Key Skills Solve 3y – 8 –y = 6 Combine like terms that are on the same side of the = sign. Solve 3y – 8 –y = 6 2y – 8 = 6 Add 8 to both sides of the = sign. + 8 + 8 2y = 14 Divide both sides of the equal sign by 2 2 2 y = 7

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
