Question

Y = 5x + 1
y = -3x – 15
5x+1=-3x-15

Answer 1

Explanation:

what do you need now ? to solve it ?

then we try to bring all terms in x on one side of the equation, and all constants on the other.

so, we add 3x to and subtract 1 from both sides.

8x = -16

and now we simply divide both sides by 8 and get

x = -2

and we are done.
