x / 3 = 17/2
x = 51/2
x = 25½
x/3+4/8 = 9
x/3+1/2 = 9
x/3 = 8 1/2
x/3 = 17/2
3 x 17 = 51
x x 2 = 2
x/3 = 51/2
x/3 + 4/8 = 9
x/3 + 1/2 = 9
6(x/3 + 1/2) = 6(9)
2x + 3 = 54
2x = 54 - 3
2x = 51
x = 51/2
x = 25.5
x/3+4/8=9
mulitply by 6
2x + 3 = 6(9)
2x = 54 - 3
x = 51/2
x/3+1/2=9
x/3=9-1/2
x/3=17/2
x=(17*3)/2=51/2
x/3+1/2=9
multiply everything by 6
u get2x+3=54
hence2x=51
x=25.5
1. divide the 4/8 to get x/3=18
2.multiply the 18 by 3 to get x=54
x/3 = 8 1/2 = 17/2
x = 51/2
x/3 + 1/2 = 9 Subtract 1/2 from both sides
x/3 = 17/2 Divide both sides by 1/3
x = 51/2
x/3 = 9 - 4/8
x/3 = 17/2
x = 51/2
