Question

find the value of X+y l,if 5x-2y=4and X+8=26​

Answer 1

Answer:

61

Step-by-step explanation:

x+8=26

x= 26-8

x=18

5x-2y=4

5×18-2y=4

90-2y=4

2y=90-4

2y=86

y=86/2

y=43

x+y=18+43= 61.

Answer 2

x+8=26

x=26-8

x=18

now,5x-2y=4

5.18-2y=4

90-2y=4

2y=4-90

y= -86/2

y=-43

x=18

y= -43

x+y= 18+(-43)

=18-43

= -25
