Question

What is the value of x in the equation 3x - 4y = 65, when y=4?

A) x=13
B) 0
C) x=217
D) x=23
E) x=27

Answer 1

The value of x in the equation 3x - 4y = 65, when y=4, is 27. option (E)

Step-by-step explanation:

To find the value of x in the equation 3x - 4y = 65, we need to substitute the given value of y, which is 4, into the equation. Here is the step-by-step calculation:

1. Substitute y with 4: 3x - 4(4) = 65.
2. Simplify the equation: 3x - 16 = 65.
3. Add 16 to both sides to isolate the term with x: 3x = 65 + 16.
4. Combine like terms: 3x = 81.
5. Divide by 3 to solve for x: x = 81 / 3.
6. Calculate the result: x = 27.

Therefore, the value of x when y = 4 is 27.
