Math Problem Statement

x=y-1 3x=2y find the points

Solution

To find the points where the system of equations intersect, let's solve the following system:

  1. x=y1x = y - 1
  2. 3x=2y3x = 2y

Step 1: Substitute x=y1x = y - 1 into 3x=2y3x = 2y

Since xx is already defined as y1y - 1 in the first equation, we can substitute this into the second equation:

3(y1)=2y3(y - 1) = 2y

Step 2: Solve for yy

Expand and simplify the equation:

3y3=2y3y - 3 = 2y

Subtract 2y2y from both sides:

y3=0y - 3 = 0

y=3y = 3

Step 3: Find xx using y=3y = 3

Substitute y=3y = 3 back into the first equation:

x=31x = 3 - 1

x=2x = 2

Solution

The solution is the point where the two lines intersect: (x,y)=(2,3)(x, y) = (2, 3)
