1/12+7/8=2/24+21/24=23/24
3/5(x-5/8)=23/24-x
one easey way is to get rid of nasty fractions
find lcd of denoms
5 and 24
hmm
24*5=120
times both sides by 120
72(x-5/8)=115-120x
distribute
72x-45=115-120x
add 120x to both sides
192x-45=115
add 45 to both sides
192x=160
divide both sides by 192
x=5/6
x=5/6

1. distribute
step 1: 3 3
× X = X
5 5
3 5 3 Ima convert this into a decimal
× - = - > negative .375
5 8 8
2. write the problem now
3 1 7
X - 0.375 = - X +
5 12 8
3. I would convert them into decimals and solve
0.6x - 0.375 = 0.08 - x + 0.875
+x +x
1.6x - 0.375 = 0.08 + 0.876
1.6x - 0.375 = 0.956
+0.375 +0.375
1.6x = 1.331
1.6 1.6
x = 0.831875
rounded up : 0.83
