15. 4(x-2) = 2(x-4)+2x i used the distributive property on the parantheses to then get... 4x-8 = 2x-8+2x I combined the like terms to then get... 4x-8 = 4x-8 +8 +8 4x = 4x which simplifies to.... x=x so the answer to question 15 is x=x
17. -4(p+1) = -2(8-2p) I used the distributive property on the parantheses.... -4p-4 = -16+4p +4 +4 -4p = -12+4p -4p -4p -8p = -12 ÷-8 ÷-8 p = 1.5
