5x + 12 + 3x = 6(x + 4)
5x+3x+12=6(x+4)
Multiply the bracket by 6
(6)(x)(6)(+4)=6x+24
5x+3x+12=6x+24
8x+12=6x+24
Move 6x to the other side. Sign changes from +6x to -6x.
8x-6x+12=6x-6x+24
8x-6x+12=24
2x+12=24
Move 12 to the other side. Sign changes from +12 to -12.
2x+12-12=24-12
2x=12
Divide by 2 for both sides.
2x/2=12/2
x=6
Answer: x=6
12kilometers
If 2cm=8km, 1cm=4km
Multiply both by three and you get that 3cm=12km
