Math Problem Statement

For the following exercises, solve the systems of linear and nonlinear equations using substitution or elimination. Indicate if no solution exists. 2.  1/2x−1/3y=4 3/2x−y=0

Solution

Let's solve the system of linear equations using substitution or elimination. The given system is:

\frac{1}{2}x - \frac{1}{3}y = 4 \tag{1} \frac{3}{2}x - y = 0 \tag{2}

Step 1: Solve Equation (2) for yy

From Equation (2): 32xy=0\frac{3}{2}x - y = 0 Solve for yy: y = \frac{3}{2}x \tag{3}

Step 2: Substitute Equation (3) into Equation (1)

Now, substitute y=32xy = \frac{3}{2}x from Equation (3) into Equation (1): 12x13(32x)=4\frac{1}{2}x - \frac{1}{3} \left(\frac{3}{2}x\right) = 4

Simplify: 12x13×32x=4\frac{1}{2}x - \frac{1}{3} \times \frac{3}{2}x = 4 12x12x=4\frac{1}{2}x - \frac{1}{2}x = 4 0=40 = 4

Step 3: Conclusion

Since we arrived at a contradiction (0=40 = 4), the system of equations has no solution.

Final Answer:

The system has no solution.
