Start with the equation ( Y = -3x + 5 ).
Substitute ( Y ) in the second equation with ( -3x + 5 ):
5x - 4(-3x + 5) = -3
Expand and solve for ( x ):
5x + 12x - 20 = -3
17x - 20 = -3
17x = 17
x = 1
Substitute ( x = 1 ) into the first equation to find ( y ):
y = -3(1) + 5
y = -3 + 5
y = 2
So, the solution is ( x = 1 ) and ( y = 2 ).
