Question

Which of the following values of x make the following functions equal? y = 2x + 1 and y = 4x – 3

Answer 1

Answer:

$2$

Step-by-step explanation:

$2x+1=4x-3$

$2x-4x=-3-1$

$-2x=-4$

$\frac{-2x}{-2}=\frac{-4}{-2}$

$x=2$

Answer 2

Answer:

2

Step-by-step explanation:

y = 2x+1

Also, y = 4x-3

Therefore,

2x + 1 = 4x - 3

2x - 4x = -3 - 1

-2x = -4

x = (-4)/(-2) = 2
