Question

2(4-2r)=-2(r+5)
6t=3(t+4)-t
2(6-4d)=25-9d
8(2f-3)=4(4f-8)
2(n+2)=5n-5
6-3d=5(2-d)
3(2f+4=2(3f-6)
5(r+3)=2r+6

solve the equtaion

Answer 1

2(4-2r)=-2(r+5)

8-4r=-2r-10

18=2r

9=r

 

6t=3(t+4)-t

6t=3t+12-t

6t=2t+12

4t=12

t=3

 

2(6-4d)=25-9d

12-8d=25-9d

d=13

 

2(n+2)=5n-5

2n+4=5n-5

9=3n

3=n

 

6-3d=5(2-d)

6-3d=10-5d

2d=4

d=2

 

5(r+3)=2r+6

5r+15=2r+6

3r=-9

r=-3
