Question

Complete the solution of the equation: -3x - 6y = -42. Find the value of y when x equals 6.

a) 7
b) 8
c) 9
d) 10

Answer 1

The value of y when x equals 6 in the equation -3x - 6y = -42 is found to be 4 after substituting x with 6 and simplifying the equation.

Step-by-step explanation:

To complete the solution of the equation -3x - 6y = -42 and find the value of y when x equals 6, we can follow these steps:

1. Substitute x with 6 into the equation: -3(6) - 6y = -42.
2. Simplify the equation: -18 - 6y = -42.
3. Add 18 to both sides: -6y = -42 + 18.
4. Simplify the right side: -6y = -24.
5. Divide both sides by -6: y = 4.

So, the value of y when x equals 6 is 4, which is not listed in the provided options (a) 7, (b) 8, (c) 9, (d) 10.
