62) 7/8x-1/4+3/4x=1/16+x
7x/8-1/4+3x/4=1/16+x
7x/8+3x/4-x=1/16+1/4
(7x+2*3x-8x)/8=(1+4*1)/16
(7x+6x-8x)/8=(1+4)/16
5x/8=5/16 cross multiply.
16*5x=8*5
80x=40
x=400
x=.5 answer.
67) 1/3x+2/5=4/15+3/5x-2/3
x/3+2/5=4/15+3x/5-2/3
x/3-3x/5=4/15-2/3-2/5
(5x-9x)/15=(4-2*5-2*3)/15
-4x/15=(4-10-6)/15
-4x/15=-12/15
-4x=-12
x=-12/-4
x=3 answer.
72)1.7t+8-1.62t=0.4t-0.32+8
1.7t-1.62t-.4t=-8-.32+8
-.32t=-.32
t=-32/-32
t=1 answer.
80) 2/3(7/8-4x)-5/8=3/8
2/3*7/8-4x*2/3-5/8=3/8
14/24-8x/3-5/8=3/8
-8x/3=3/8+5/8-14/24
-8x/3=8/8-14/24
-8x/3=(24-14)/24
-8x/3=10/24 cross multiply
-8x*24=3*10
-192x=30
x=30/-192
x=-10/64 answer.
