Answer 2

1) 2/3 (x-5) -1/4 (x-2) = 9/2
2x/3 - 10/3 - x/4 + 10/3 - 1/2
2x/3 - x/4 = 9/2 + 10/3 - 1/2
5x/12 = 85/6
5x = 170
x = 34
2) 3 (3m-10) =2m+5
9m -30 = 2m+5
9m-3m = 5+30
7m = 35
m = 5
3) t - 2t - 5 - 5 + 10t = 6 + 8t - 3t + 12
9t - 10 = 18 + 5t
9t - 5t = 18+ 10
4t = 28
t = 7
4) 4(y-1)-3(y-2)/3×4=1
4y-4-3y+6/12=1
4y-3y+6-4=12
y+2=12
y=12-2
y=10
5) 0.5x-0.6x=0.2-0.3x
0.5x+0.3x-0.6x=0.2
0.2x=0.2
X=1
7) 3x+x= 2-2/5
4x = (10-1)/5
x=(9/5)/4
x=9/5×1/4
x= 9/20
