Solve each pair of equation by using the substitution method. 3x-5y=-1 and x-y=-1.

Solve the following system of equations by using the method of substitution: 3x-5y=-1,quad x-y=-1

Solve :x-y=-1 and 3x-5y=-1 by substitution and equating coefficients.

The factors of x^3-1+y^3+3x y are (a) (x-1+y)(x^2+1+y^2+x+y-x y) (b) (x+y+1)(x^2+y^2+1-x y-x-y) (c) (x-1+y)(x^2-1-y^2+x+y+x y) (d) 3(x+y-1)(x^2+y^2-1)

1/(3x+y)+1/(3x-y)=3/4 and 1/(3x+y)-1/(3x-y)= -1/4
