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.
