The system of equations can be solved using linear combination to eliminate one of the variables.
2x β y = β4 β 10x β 5y = β20
3x + 5y = 59 β 3x + 5y = 59
13x = 39
Which equation can replace 3x + 5y = 59 in the original system and still produce the same solution?
2x β y = β4
10x β 5y = β20
7x = 39
13x = 39
