5d+3d = 15 8d = 15 d = 15/8 = 1.875

8d = 5d+18 8d-5d = 18 3d = 18 d = 6

I--2a+b=2c+2d II--2a+b=c+2d III--a+2b=3d * Here if we perform (I)-(II), we get, c=0 * Using the c we can prove b=0 using (I)-(III). * Now replace 'b' & 'c' as 0 in (I), then we get a=d. Email me at yash2008gates@gmail.com for any queries. I will be very thankful to receive your queries.

2(3d+7)=5+5d. 6d+14=5+5d 6d+9=5d 9=-1d d=-9 I think that's correct. If it is, ur welcome.

It is an expression and can be simplified to: 3d+f+1

3d + 14 = 11 is the equation.

No. 1a and 3d are linear, but 2bc is not. ■

1.6-d=12.8+3d 12.8-1.6=-d-3d 11.2=-4d 11.2/-4=d d=-2.8

So you basically have, (27D-9)+3D = 29+(27D+1) 30D-9 = 27D+30 3D = 39 D = 13

5d+3d = 15 8d = 15 d = 15/8 = 1.875

c = 6 and d = 7

D + 3D = 240 4D = 240 Divide both sides of the equation by 4: D = 60

3d-3d cancel 2d-3d=-1d 8=-1d-17 -17+17 cancel 8+17=25 25=-1d 25/-1=-1d/-1 d=-25

1. 7d-13=3d+72. 7d-20=3d3. -20=-4d4. d=55. Check your answer:7*5-13=22, 3*5+7=22D equals 5

8d = 5d+18 8d-5d = 18 3d = 18 d = 6
