Answer 1

3.

t=3/4(t-2)

t=3t/4-6/2

t-3t/4=-6/2

4t-3t/4=-6/2

t/4=-6/2

2t=-24

t=-12

4.

2y/5-3=5y/6+10

2y/5-5y/6=10+3

12y-25y/30=13

-13y/30=13

y=13*30/-13

y=-30

5.

7x+5=3(x-4)+1

7x+5=3x-12+1

7x-3x=-11-5

4x=-16

x=-16/4

x=-4

6.

2t-5/6=11/15-45t

2t+45t=11/15+5/6

47t=22+25/30

47t=47/30

t=47/30*47

t=30

7.

0.4(3x-1)=0.5x+1

2/5(3x-1)=1/2x+1

6/5x-2/5=1/2x+1

6/5x-1/2x=1+2/5

12x-5x/10=5+2/5

7x/10=7/5

35x=70

x=70/35

x=2
