Question

Find the solution of given linear equation :

7+4y/
y+z

= −4/3​

Answer 1

Answer:

systems of linear equations using a strategy called elimination. First, we need to understand that it's okay to add equations together.

Key idea: Anytime we have two true equations, we can add or subtract them to create another true equation.

For example, here are two very basic true equations:

2 = 22=22, equals, 2

5 = 55=55, equals, 5

We can add these equations together to create another true equation:

2+ 57=2=5=7
