Question

Find x and y in the following:​

Answer 1

Answer:

(a) x+8y=29

X=5

5+8y=29

8y=29-5

8y=24

Y=24/8

Y=3

(5,3)

(b) x+3y=14

(X=2)

2+3y=14

3y=14-2

3y=12

Y=12/3

Y=4

(2,4)

Answer 2

Answer:

X = 5  ;    Y = 3

Step-by-step explanation:

x + 8y = 29

x = 29 - 8y

x + 3y = 14

29 - 8y + 3y =14

29-5y =14

-5y= 14-29

-5y = -15

y = -15/-5

y = 3

APPLY THIS TO X

x = 29 - 8y

x = 29 - 8 * 3

x = 29 - 24

x= 5
