Math Problem Statement

3x - 4y = 6

Solution

The equation 3x4y=63x - 4y = 6 represents a linear equation in two variables, xx and yy. There are different ways to handle this equation depending on what you're looking to find:

1. Solving for One Variable:

If you want to express one variable in terms of the other, you can solve for yy or xx.

Solving for yy: 3x4y=63x - 4y = 6 Subtract 3x3x from both sides: 4y=3x+6-4y = -3x + 6 Divide by 4-4: y=3x64=3x464=3x432y = \frac{3x - 6}{4} = \frac{3x}{4} - \frac{6}{4} = \frac{3x}{4} - \frac{3}{2}

Solving for xx: 3x4y=63x - 4y = 6 Add 4y4y to both sides: 3x=4y+63x = 4y + 6 Divide by 33: x=4y+63=4y3+2x = \frac{4y + 6}{3} = \frac{4y}{3} + 2

2. Finding the Intercepts:

You can also find the intercepts of the line represented by this equation.

x-intercept (when y=0y = 0): 3x4(0)=6    3x=6    x=23x - 4(0) = 6 \implies 3x = 6 \implies x = 2 So, the x-intercept is (2,0)(2, 0).

y-intercept (when x=0x = 0): 3(0)4y=6    4y=6    y=323(0) - 4y = 6 \implies -4y = 6 \implies y = -\frac{3}{2} So, the y-intercept is (0,32)(0, -\frac{3}{2}).

3. Graphing the Equation:

To graph the equation, you can plot the intercepts (2,0)(2, 0) and (0,32)(0, -\frac{3}{2}) on a coordinate plane and draw a line through these points.
