Just like the quadratic formula. I have made a linear formula as i was thinking through how the quadratic formula (making x the subject of ax^2 + bx + c = 0) so i also made x the subject of the standard linear equation

y=mx+c

y-c=mx+c-c

y-c=mx

(y-c)/m=(mx)/m

(y-c)/m=x

PROOF

Solve;

1) 15=2x+3

x=(y-c)/m

x=(15-3)/2

x=12/2

x=6 CORRECT
