Question

Solve the following equation: 6y – 20 = 2y – 4.

Answer 1

subtract 2y from both sides first \[\implies 6y - 20 - 2y = 2y - 4 - 2y\]
combine like terms \[\implies 4y - 20 = -4\]
now add 20 to both sides
\[\implies 4y - 20 + 20 = -4 + 20\]
combine like terms \[\implies 4y = 16\]
now divide both sides by 4 \[\implies \frac{4y}{4} = \frac{16}{4}\]
simplify \[\implies y = 4\]
does that help?
