Given the equation:
x + 2y = -6
Solve for x.
Determine the coefficient of y.
Solution:
The coefficient of y is simply the number that is attached to y. In our case we have the number 2.
Coefficient of y = 2
In order to solve for x, we simply must transpose 2y to the other side of the equation, hence it must be taken to note that in transposing a number, the sign of the number changes.
x + 2y = -6
x = -6 - 2y
Final answer:
Coefficient of y = 2
x = -6 - 2y
