Question

2x+3y=8 & 8x-16=40 then find the value of x and y please help me this question​

Answer 1

the answer is. x=7 and y=. -2

Step-by-step explanation:

2x+3y=8. 8x-16=40

=2x=8-3y. =8×(8-3y/2)-16=40

=x=8-3y/2. (eq___1) =4×(8-3y)-16=40

=32-12y-16=40

=16-12y=40

=. -12y=40-16

=y=24/-12

=y=. -2

Therefore, eq____1

x=8-3×(-2)/2 (•.•y= -2)

x =8+6/2

x=14/2=7

x=7 and y=-2
