Question

2x+3y=8 & 8x-16=40 then find the value of x and y​

Answer 1

Step-by-step explanation:

8x-16=40

8x = 40-16

8x = 56

x = 56/8

x=7

now putting the value of x in (2x+3y=8)

2x+3y=8

2(7)+3y=8

14+3y=8

3y=8-14

3y= -6

y= -6/3

y=-2

Answer 2

8x-16= 40

8x = 40+16

8x = 56

x = 7

2x+3y=8

2(7)+3y=8

14+3y=8

3y= 8-14

3y= -6

y=-2

formula = substitution method

hope this helps you
