y = 3x 3x + 4y = 30 3x + 4(3x) = 30 3x + 12x = 30 15x = 30 x = 2 y = 3x y = 3(2) y = 6 (2, 6)
-5x-4y = 6 -4y = 5x+6 Divide all terms by -4 y = -1.25x-1.5 Slope = -1.25 and intercept = -1.5
-1.5
3x-4y = 8 -4y = -3x+8 y = 3/4x-2 or y = 0.75x-2 which is the equivalent in slope intercept form
6y 10+4y subtract 4y from each side 2y 10 divide both sides by 2 y = 5
4y+2 = 2y+6 4y-2y = 6-2 2y = 4 y = 2
3x-2y=24 (1)6x-4y=-6 (2)(1) => 6x-4y=48 [(1)*2](1)*2=(2)therefore:6x-4y = -6 AND 48-6 ≠ 48the equation cannot be solved
2 - 8y + 6 = 4y - 702 + 6 + 70 = 4y + 8y78 = 12yy = 78/12y = 6.5
If x - 4y = 2 and x + 4y = 2 then the only solution is when y = 0 and thus x = 2.
y=2
6-4y = 2
4y-9 = 15 4y = 15+9 4y = 24 y = 6
If you mean 6x + 4y, then 4y=(-6x+24) y=(-6x+24)/4= y=(-3/2)x+6 b=6 If you mean 6x - 4y then -4y=(-6x+24) y=(-6x+24)/-4 y=(3/2)x-6 b=-6
6X - 4Y = 24 - 4Y = -6X + 24 Y = 3/2X - 6 slope(m) = 3/2 Y intercept = - 6
If x=2, then 7x = 14 and if y=5 then 4y=20.
y= 3/6 which reduces to 1/2
