I need help on these three questions BEFORE 10:00 PM. Please someone show me how to do them step by step!
Solve the equation for y in terms of x
then find the solutions of the equation for the given values of x.
1.x + y = -1 [values of x: 3, 1, -2]
2.x+ 4y = 20 [values of x: 4, -8, 0]
3.-x - 2y= 8 [values of x: -6, -2, 10]
Thanks a MILLION!!
