x = 3 and y = 0
2x + 3y = 12 x = 1.45, so 2 * 1.45 + 3y = 12 2.9 + 3y = 12 3y = 12 - 2.9 = 9.1 y = 9.1/3 = 3.0333... or 91/30 or 3 1/30.
5x+3y
(3, 2) because x = 3 and y = 2
30 - 12 = 18
perpendicular
x = 3y - 3 so 6 (3y - 3) + 2y = -12 ie 18y - 18 + 2y = -12 ie 20y = 6 so y = 0.3 and x = -2.1
The slope is -1. 3x+3y=12 Subtract 3x 3y=-3x+12 Divide by 3 y=-x+4
x = 3 and y = 2
To solve the equation (2x + 3y = 12) for (x), first, isolate (2x) by subtracting (3y) from both sides, giving (2x = 12 - 3y). Then, divide both sides by 2 to solve for (x): (x = \frac{12 - 3y}{2}). Simplifying further, (x = 6 - \frac{3y}{2}).
