4x - 3y = 12-3y = -4x + 12y = (4/3)x - 4^plug this transformed version of the equation into your graphing calculator or do it out by hand.
4x + 3y = 8x + y so 3y - y = 8x - 4x ie 2y = 4x so y = 2x
Normally, this is a difficult form of the equation to deal with. To change it into a more familiar form, we can do this: 4x + 3y = 0 3y = -4x y = (-4/3)x
4x + 3y = 7 y = [(-4)/3] x + 7/3
4x - 3y = -6Add 3y to each side:4x = -6 + 3yAdd 6 to each side:4x + 6 = 3yDivide each side by 3:(4/3)x + 2 = yThe graph is a straight line with a slope of (4/3) and a y-intercept of 2 .
3y - 4x = 24 The first step is to write it in the standard form (y=mx + c) 3y = 4x + 24 y = (4x + 24)/3 y = 4x/3 + 8 The y-intercept is 8 and the slope/gradient is 4/3
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?
x - 3y = 11 So x = 11 + 3y Then, by the other equation, 4x + 3y = -1 becaomes 4(11+3y) + 3y = -1 or 44 + 12y + 3y = -1 or 15y = -45 so that y = -3
3y = 4x + 9 -4x + 3y = 9 is the standard form
-4x + 3y = 9
y = -24x - 3y = 18 (use the substitution method)4x - 3y = 18 (substitute -2 for y, and solve for x))4x - 3(-2) = 184x + 6 = 18 (subtract 6 to both sides)4x = 12 (divide by 2 to both sides)x = 3Thus, (3, -2) is the solution of the given system of equations.
3y=4x+9.....-4xAnswer: 4x-3y=9
