SOLUTION: i Just Barely Learned This Type of Equations im Just Lost on Ways To Answer it.. 6x - y = -145 x = 4 - 2y Do i distribute after i substitute (4-2y) for x? Also How many

Question 634505: i Just Barely Learned This Type of Equations im Just Lost on Ways To Answer it..
6x - y = -145
x = 4 - 2y
Do i distribute after i substitute (4-2y) for x?
Also How many different way are there to sove an equation like these, 2, Substitution and addition? Are there more? Look @ Example Below
EXAMPLE: DONT SOLVE JUST PLEASE ANSWER QUESTION BEFORE
-11x - 10y = 17
5x - 7y = 50
:D THANK YOU (IM STUPID !)

What you call addition is often called elimination because one of the terms is eliminated.
Generally, just the two ways until you get into matrices which is part of linear algebra.
Yes distribute after substituting.
