What is the solution of the system of equations? {4x−3y=152x+2y=4

Start by solving one equation for x or y, this time I'm choosing x. 2x = 4 - 2y, then x = 2 - y. Now substitute in x in the other equation. 4(2-y) - 3y = 15. This simplifies to 8 - 4y - 3y = 15. This simplifies to -7y = 7. Divide both sides by -7, and y = -1. Now plug the y value into the other equation: 2x + 2(-1) = 4. This simplifies to 2x = 6, and x = 3. 
X = 3, Y = -1   or (3,-1)

This organelle is responsible for controlling the cell's activities. 1.Mitochondria 2.Ribosome 3.Nucleus 4.Endoplasmic Reticulum
Inga [223]
Hi there,

The Mitochondria is the power house of the cell. It provides energy for the cell therefore that is out.

The Ribosome breaks down and produces protein for the cell therefore that is out.

The Endoplasmic Reticulum allows protein to pass through in vacuoles therefore that's out as well.

The Nucleus acts as a brain controlling other organelles therefore it's the Nucleus.

So the answer is 3.

Hope this helps!
