Question

) Solve the following simultaneous equations
(i) 2x + y = 5, 3x - y = 5​

Answer 1

Answer:

2x+y=3x-y

y+y=3x-2x

2y=x

Putting x = 2y in equation 3x-y

3×2y-y =5

5y=5

Y=1

Putting y=1 in 2y=x

2×1=x

x=2

Answer 2

Answer:

x=2 y=1

Step-by-step explanation:

2x + y = 5 ——(1)

3x - y = 5 .——(2)

adding 1 and 2

2x+y+3x-y = 5+5

5x = 10

x = 2

substituting the value of x in equation 1

2(2) + y = 5

4 + y = 5

y = 5–4

y = 1
