Question

(i) if 2x + y = 12 and 3x - y = 13, find the value of x.​

Answer 1

Answer:

2x+y=12....(1)

3x-y=13....(2)

add (1)from(2)

3x-y=13

2x+y=12

5x=25

x=25/5

x=5

Answer 2

Answer:

x = 1

Step-by-step explanation:

2x + y + 1 = 13 = 3x - y

2x + y + 1 = 3x - y

y - y + 1 = 3x - 2x

1 = x

Therefore, x = 1.
