By each step and simplification, it is proven that the y = -9 from the equation 2/3y + 15 = 9.
What is a system of equations?
A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Given;
2/3y + 15 = 9
Subtract 15 from both sides, we get,
2/3y + 15 - 15 = 9 - 15
Now Simplify:
2/3y = -6
then, Multiply each side by 3:
3 (2/3y) = 3 (-6)
2y = -18
Divide both sides by 2:
2y / 2 = -18/2
y = -9
Therefore, By each step and simplification, it is proven that the y = -9 from the equation 2/3y + 15 = 9.
