Given the numerical equation:
9y - y - 7y + 3
Simplify the equation.
Solution:
In order to simplify the given equation, we simply need to combine like terms. That means, we only combine terms with y, and constants.
= 9y - y - 7y + 3
= 8y - 7y + 3
= y + 3
Simplified form = y + 3
In order to solve for y, we simply need to transpose 3 on the other side of the equation, hence it must be taken to note that in transposing a number, the sign changes.
y = -3
Final answer:
Simplified form = y + 3
y = -3
