-4x + 3y = 9
4x + 3y = 7 y = [(-4)/3] x + 7/3
3y = 4x + 9 -4x + 3y = 9 is the standard form
You need to organise your question properly. 3x+2y=4 4x + 3y= 7? Is 4 4x = 44x or 4-4x or 4+4x How can there be 2 equal signs in 1 equation?
4x + 3y=9 x=0 y=3
4x+3y = 12 3y = -4x+12 y = -4/3x+4
4x+3y = 6 3y = -4x+6 y = -4/3x+2 in slope intercept form
To solve for 2 unknown variables you need 2 independent equations. You have only 1.
x = 3 and y = 0
4x + 3y = 6y 4x = 3y 4/3 x = y The slope is 4/3 and the y intercept is 0.
