Question

Q14. Find the values of x and y
in the following rectangle.
x+3y
3x+
13
5

Answer 1

Answer:

x=86/5

y= -7/5

Step-by-step explanation:

x+3y =13........(1)

3x+y = 7..........(2)

by (1) equ.

x= 13-3y........(3)

this value of x placed in equ. (2) than

3(13-3y) =7

y = -7/5

this value of y placed in equ. (3) than

x = 86/5

Answer 2

Answer:

X=3 and Y=4

Step-by-step explanation:

Opposite sides of rectangle are equal

3x+y =7 ...eq 1 and x+3y=13...eq2

Multiplying eq2 with 3 and subtracting eq1 from 2,

3x+9y=39

(-) 3x+y=7

—————-

8y=32

Y = 4

Substitute in eq1, we get

X+4=7

X=3
