Question

What is y=4x-1 and 2x+y=23 as an ordered pair

Answer 1

x,y=(4, 15)

Explanation:

We need to substitute the value of y=4x-1 and plug it into the equation 2x+y=23.

By this we get:

2x+4x-1=23

6x-1=23

6x=24

x=4

We can now solve for y using the given value of x.

2x+y=23

2×4+y=23

8+y=23

y=23-8

y=15

Explanation:

Answer 2

x,y=(4, 15)

Explanation:

We need to substitute the value of y=4x-1 and plug it into the equation 2x+y=23.

By this we get:

2x+4x-1=23

6x-1=23

6x=24

x=4

We can now solve for y using the given value of x.

2x+y=23

2×4+y=23

8+y=23

y=23-8

y=15

Hope this helps!
