-8x + 12y = 24
Algebraically rearrange
12y = 8x + 24
Reduce by a factor of '4'
3y = 2x + 6
Divide both sides by '3'
y = (2/3)x + 2
Hence it is a straight line of slope/gradient ' 2/3' and a y-intersect of '2'.
6x - 12y = 24 Algebraically rearrange -12y = -6x + 24 Multiply both sides by '-1' Hence 12y = 6x - 24 Factor out '6' on both sides. 2y = x -4 Divide both sides by '2' y = (1/2)x - 2 Hence the gradient is ' 1/2' and the y-intersect is ' - 2' .
It equals 24.
first add 12 plus 12 equals 24, then add 4 plus 4 and that equals 8. 24 plus 8 equals 32. 12 + 12 = 24 4 +4 =8 24 + 8 =32
x equals 25
The equation seems to equal 72.
6x - 12y = 24 Algebraically rearrange -12y = -6x + 24 Multiply both sides by '-1' Hence 12y = 6x - 24 Factor out '6' on both sides. 2y = x -4 Divide both sides by '2' y = (1/2)x - 2 Hence the gradient is ' 1/2' and the y-intersect is ' - 2' .
Add 3y to each side: 12y = 24 Divide each side by 12: y = 2.
15x+12y+22+3w-2y+3x+14-12+3w original = 15x+3x+12y-2y+3w+3w+22+14-12 group = 18x+10y+6w+24 answer
-5x + y = -12- 3x + 6y = -12Since both of expressions have a value of -12, their sum is - 24. This is true only whenx = 20/9 and y = -8/9.-5x + y = -12y = 5x - 12- 3x + 6y = -12-3x + 6(5x - 12) = -12-3x + 30x - 72 = -1227x = 60x = 60/27x = 20/9y = 5x - 12y = 5(20/9) - 12y = 100/9 - 12y = (100 - 108)/9y = -8/9
x-intercept:2x = 24x = 12y-intercept:-3y = 24y = -8
It equals 24.
24 + 24 + 24 + 24 = 24 x 4 = 96
it equals 70
first add 12 plus 12 equals 24, then add 4 plus 4 and that equals 8. 24 plus 8 equals 32. 12 + 12 = 24 4 +4 =8 24 + 8 =32
12+12
x equals 25
The equation seems to equal 72.
