Final answer:
Upon substituting x = 7/4 and y = 3/4 into 4x + 7y = 3, the result is not equal to 3, indicating that these values do not satisfy the equation.
Step-by-step explanation:
The question asks to solve for the values of variables x and y in the given linear equation 4x + 7y = 3. To find the solution, we substitute the given values of x = 7/4 and y = 3/4 into the equation to see if they satisfy it. The process involves multiplying 4 by x and 7 by y, then adding the results to see if the sum is equal to 3.
Let's substitute the given values:
-
- 4(7/4) + 7(3/4)
-
- 7 + 21/4
-
- 28/4 + 21/4
-
- (28 + 21) / 4
-
- 49/4
-
- 12.25, which is not equal to 3
Since 12.25 is not equal to 3, the values x = 7/4 and y = 3/4 do not satisfy the equation 4x + 7y = 3, which indicates there might be an error in the values given for x and y. The correct solution for x and y would make the equation hold true.
