Question

How many solutions does the system have?

x = -4y + 4
2x + 8y = 8

Answer 1

x = -4y + 4
2x + 8y = 8 --> this one can be written as 2x=-8y+8

thus the system is
x = -4y + 4
2x = - 8y + 8

notice that if you multiply the first equation by 2 you'll get the second

thus it is an infinite system having infinite number of solutions

Answer 2

Thank that really helped I was stuck
