Math Problem Statement

Solve the system of equations: 5x + 2y = 1 and 3x + 2y = 3.

Solution

The image shows a system of linear equations:

5x + 2y = 1 \\ 3x + 2y = 3 \end{cases}$$ To solve this system, we can use the elimination method. Here's the step-by-step process: 1. **Subtract the second equation from the first** to eliminate $$2y$$: $$(5x + 2y) - (3x + 2y) = 1 - 3$$ Simplifying this, we get: $$2x = -2$$ 2. **Solve for $$x$$**: $$x = \frac{-2}{2} = -1$$ 3. **Substitute $$x = -1$$ into the first equation** to solve for $$y$$: $$5(-1) + 2y = 1$$ Simplify this equation: $$-5 + 2y = 1$$ Add 5 to both sides: $$2y = 6$$ 4. **Solve for $$y$$**: $$y = \frac{6}{2} = 3$$ **Solution**: $$x = -1$$ and $$y = 3$$. Would you like a more detailed explanation of any of these steps, or do you have any questions? ### Related Questions: 1. How can you solve the system using substitution? 2.
