distributive property

Question

solve the equation

3(2x+2)-4(x-5)=18

Answer 1

Apply distributive property.
3(2x+2)-4(x-5)=18 Multiply the coefficents of given problem. 6x + 6 - 4x + 20 = 18       Combine like terms. 2x + 26 = 18 Subtract 26 from each side. 2x + 26 - 26 = 18 - 26 2x = -8 Divide each side by 2. 2x⁄2 = -8⁄2 x = -4 The solution of x = -4.
