Hint: There are many ways to solve a system of linear equations . You can directly solve them using algebra or draw them on graphs. One of the many ways is to add one equation to the other.
Complete step-by-step answer:
We have the first equation,
3x – 2y = 4, let us call it equation 1
and
-3x + 5y = -7, equation 2
Now add equation 2 to equation 1
3y = -3
y = -1
And putting the value of y in any one of these two equations
We get ,
3x + 2 = 4
Note: A system of linear equations is when we have two or more linear equations working together . This question could also be done by substitution of variables and also by constructing a graph.
