Question

2x-y=3,4x-y=5 by substitution mathod?​

Answer 1

Answer:

solve by substitution method:- 2x-y=3 4x-y=5

• from eq(1): substituting the value of y from eq(1) in eq(2):
• put x = 1 in eq(1):
• thus x = 1 and y = -1 is the solution of the given equation. hope this helps you. cheers!!

Answer 2

Answer:

The value of x is 1 and y is -1

Step-by-step explanation:

2x - y = 3 -- (1)

4x - y = 5

y = 4x - 5 ---(2)

substitute value of y in eq.--(1)

2x - (4x - 5) = 3

2x - 4x + 5 = 3

-2x + 5 = 3

2x = 5 - 3

2x = 2

x = 2/2

x = 1

substitute value of x in eq.--(2)

y = 4(1) - 5

y = 4 -  5

y = -1
