We have two equation with two unknowns. Therefore, we can solve the x and y easily. There are a number of methods to apply here but I will be using substitution method. We do as follows:
-2x + y = 1
y = 1 + 2x
4x + y = -1
4x + 1 + 2x = -1
6x = -1 -1
6x = -2
x = -1/3
y= 1 + 2(-1/3)
y = 1/3
Step-by-step explanation:
–6(x + 5) + 3 = –2(x + 4) – 4x
–6x – 30 + 3 = –2x –8 – 4x
–6x –27 = –6x –8
–6x + 6x = –8 + 27
0 = 19
no solution
sin (x) = -1
arcsin (-1) = x
x = -90
and multiples of 360
x =-90, 270,....
x =-90 + 360n where n is an integer
or in radians
-pi/2 + 2*pi *n where n is an integer

Step-by-step explanation: Binomials are the sums of two terms (the sum two monomials). Therefore those with two terms being added are considered binomials.
