What is the answer to (6.9); x + 6y = 5

To find the solution to the equation x + 6y = 5 when x = 6.9, we need to substitute the value of x into the equation and then solve for y.

Given: x + 6y = 5

Substituting x = 6.9 into the equation, we have:

6.9 + 6y = 5

Now, let's solve for y:

First, we can simplify the equation:

6y = 5 - 6.9

Combining the numbers:

6y = -1.9

Next, we divide both sides of the equation by 6 to isolate y:

y = -1.9 / 6

Evaluating the division:

y ≈ -0.3167

Therefore, when x = 6.9, the solution to the equation x + 6y = 5 is y ≈ -0.3167.
