2. y=1-4x and y=2x+13

Question

Please show work, need help badly

Answer 1

I'm assuming you are trying to solve for x and y? What you need to do is solve one equation for either x or y, and then plug that solution into the other equation.

y= 1-4x

so

y = 2x + 13 turns into 1 - 4x = 2x + 13

solving this leads to

6x = -12

x = -2

now we can use our value of x to solve for y!

y = 1 - 4(-2)

y = 9

so x = -2, y=9
