Question

solve x+y=34 and x-y=4​

Answer 1

Answer:

Let x be y + 4

y + y + 4 = 34

2y + 4 = 34

2y = 34 - 4

2y = 30

y = 30 / 2

y = 15

y = 15

x = 19

Answer 2

Answer:

x=19,y=15

Step-by-step explanation:

Let x be y + 4

y + y + 4 = 34

2y + 4 = 34

2y = 34 - 4

2y = 30

y = 30 / 2

y = 15

therefore,

y = 15

x = 19
