The value of x is -3.5 and y is 6.5 for the given equations.
What is an equation?
An equation is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
The equations will be solved as:-
−3x + y = 4
−9x + 5y = −1
Multiply the first equation by 3 and subtract the second equation.
−15x + 5y = 20
9x - 5y = -1
--------------------
-6x = 21
x = -3.5
Put x = -3.5 into first equation.
(-3x3.5) + y = 4
y = 6.5
Hence, the values are -3.5 and 6.5.
