Question

substitute y=2x-7 in the equation x-2y=-1.find the values of x and y​

Answer 1

Answer:

x = 5 , y = 3

Step-by-step explanation:

y = 2x - 7

Substituting the value of y in the equation =>

x - 2y = -1

x - 2(2x - 7) = -1

x - 4x + 14 = -1

-3x = -1 - 14

-3x = -15

x = -15/-3

x = 5

Now,

y = 2x - 7

y = 2×5 -7

y = 10 - 7

y = 3

Please check, whether it's correct or not.
