a) 5x – 24 = 3(x-16)
5x-24=3x-3*16
5x-24=3x-48
5x-3x=-48+24
2x= -24
x= -24/2
x= -12
c) 3(2x + 2) – 5x + 4= 7(1-2) +24
6x+6-5x+4=7-14+24
x=7-14+24-6-4
x=7
e) 5(x + 4) -46-5)= 6(x+ 7) +3
5x+20-46-5=6x+42+3
20-46-5-42-3=6x-5x
-76=x
x=-76
g) 2(x-3) +207 – 20) = (r+ 5) + 31
2x-6+207-20=r+5+31
2x-r=5+31+6-207+20
2x-r=-145
x-r= -145/2
