Solve the following system of equations algebraically

3x - y = 0
5x + 2y = 22

anonymous · Answer

Does it matter if it's substitution or elimination?

radar · Answer

from the first we get y = 3x

radar · Answer

substitute for y in the 2nd equation.
5x + 6x = 22
11x = 22     solve for x and then solve for y.

anonymous · Answer

Its says :
Multiply one of the equations by a constant in order to solve by elimination.

radar · Answer

Oh, you just said algebraically.

anonymous · Answer

I mean thats what the question says...

radar · Answer

Multiply the first equation by 2 then add and solve for x.

anonymous · Answer

Okay so you were right. 11x = 22 so x = 2

radar · Answer

6x - 2y = 0
5x + 3y =22
------------
11x = 22
