Question

Solve for y 6y-20=2y-4

Answer 1

First:
$6x - 2y = 20 - 4 \\ 4x = 16 \\ x = \frac{16}{4} \\ x = 4$
Answer.
$x = 4$

Answer 2

6y-20=2y-4

6y + -20 = 2y + -4

-20 + 6y = 2y + -4

-20 + 6 y = -4 + 2y

-20 + 6y + -2y = -4 + 2y + -2y

-20 + 4y = -4 + 2y + -2y

-20 + 20 + 4y = -4 + 20

4y = 16

y = 4
