Question

Select all of the correct solutions for the following equation

22 – 2 = 4.1 - Y-1
(1,3)
(3,1)
(-1-3)
None of the above

Answer 1

(1,3)

Explanation:

2x-2=4x-y-1

subtract 2x on both sides

-2=2x-y-1

add y on both sides

y-2=2x-1

add 2 on both sides

y=2x+1

now we can just kinda plug and check.

if you plug in 1, you get 3, so A
