Problem 1

subtract 3 x

5y=-3x+11

divide 5

y=3/5x+2.2'

Problem 2

add 5x

7y=5x+9

divide 7

y=5/7x+1.3'

'notice'

you can put 2.2 into a fraction (11/5) and 1.3 (9/7) if your teacher allows it, but i put them into decimals

D=DVDs and G=Games solve for 2D+3G=15.50 and 3D+1G=12.05

kogti [31]

We have

1G = 12.05 - 3D;

Then,

2D + 3( 12.05 - 3D) = 15.50;

2D + 36.15 - 9D = 15.50;

- 7D = - 20.65;

D = 2.95;

Finally, G = 12.05 - 3 x 2.95;

G = 3.20;
