3x + 2y = 12 ie 2y = 12 - 3x so y = 6 - 3x/2
8a+4a=144 12a=144 12a/12=144/12 A=144
To solve this, you should first write it as an equation (where 'x' is the unknown value):8x = 12Then you can solve for x:8x =12X = 12/8X=1.5
-9h-6+12h+40=22 -9h+12h=22-40+6 3h=-12 h=-4
The equation 6 + y = 12 is a simple equation in one variable. If you add 6 to both sides of the equals sign, you get y = 18, and that is the solution.
-0.5
X = 12
the answer is-10 = 12 +xx= -10-12x=-22this is the answerx= -22
b = 14
3x + 2y = 12 ie 2y = 12 - 3x so y = 6 - 3x/2
The solution to this equation is that h is equal to -4. You can substitute this value for h into the equation to get -4 x -9 - 6 plus 12 x -4 plus 40 equals 22, or 36 - 6 plus - 48 plus 40 equals 22.
8a+4a=144 12a=144 12a/12=144/12 A=144
4y + 7 = 19 ∴ 4y = 12 ∴ y = 3
If you solve such an equation for "y", you get an equation in the slope-intercept form.
12/3 = 4
3t + 7 = 2t - 5 3t = 2t - 12 t = -12
12 + 5 equals...
