Math Problem Statement

Solve the system of equations graphed on the coordinate axes below. y, equals, start fraction, 3, divided by, 2, end fraction, x, minus, 1 y= 2 3 ​ x−1 y, equals, minus, start fraction, 3, divided by, 2, end fraction, x, plus, 5 y= − 2 3 ​ x+5

Solution

The system of equations given is:

  1. y=32x1y = \frac{3}{2}x - 1
  2. y=32x+5y = -\frac{3}{2}x + 5

To solve this system of equations, we need to find the point of intersection, which means solving for xx and yy where both equations are equal.

Step 1: Set the equations equal to each other

Since both expressions represent yy, we can set them equal to each other:

32x1=32x+5\frac{3}{2}x - 1 = -\frac{3}{2}x + 5

Step 2: Solve for xx

Now, add 32x\frac{3}{2}x to both sides to eliminate the term from the right side:

32x+32x1=5\frac{3}{2}x + \frac{3}{2}x - 1 = 5

This simplifies to:

3x1=53x - 1 = 5

Next, add 1 to both sides:

3x=63x = 6

Now, divide both sides by 3:

x=2x = 2

Step 3: Solve for yy

Now that we have x=2x = 2, substitute it into either of the original equations to find yy. I'll use the first equation:

y=32(2)1y = \frac{3}{2}(2) - 1

Simplify:

y=31=2y = 3 - 1 = 2

Final Solution:

The solution to the system of equations is (x,y)=(2,2)(x, y) = (2, 2).
