Answer 2

To solve the system of equations:

U + 2V = 11 ...(1) 5U - 3V = 3 ...(2)

There are multiple methods to solve this system of equations, but one common approach is to use the method of substitution. Here's how you can solve it step by step:

Step 1: Solve equation (1) for U. From equation (1), we have U = 11 - 2V.

Step 2: Substitute the value of U in equation (2). Substituting U = 11 - 2V into equation (2), we get: 5(11 - 2V) - 3V = 3.

Step 3: Solve for V. Expanding the equation, we have: 55 - 10V - 3V = 3. Combining like terms, we get: -13V = -52. Dividing both sides by -13, we find: V = 4.

Step 4: Substitute the value of V into equation (1). Using V = 4 in equation (1), we have: U + 2(4) = 11. Simplifying, we get: U + 8 = 11. Subtracting 8 from both sides, we find: U = 3.

Therefore, the solution to the system of equations is U = 3 and V = 4.
