How can you solve a system of two linear equations with two variables by writing each equation in the equivalent mx+b

Question

I can’t do this I need for today or tomorrow please:(

Answer 1

y = mx + b

y =nx + c

nmx+b = nx +c

mx-nx = c-b

x = (c-b)/(m-n)

y = m(c-b)/(m-n)

or try a specific example

y=2x + 3

y=x -4

2x+3 = x-4

2x-x = -4-3

x = -7

y =x-4 =-7-4 = -11
