As provided, it extremely is secure to assert it extremely is an removing subject. this is why: in case you upload them, you will get: y=2x-3 + y=5x-18 _______ 2y=7x-21 which leads us especially plenty nowhere. yet whilst u "do away with" y via making: 2x-3=5x-18 3x=15 x=5 now replace x on any of the unique equations to get y y=2*5-3 y=7 you will get the outcomes. whether it extremely is honestly all with regard to the variety you notice it, by way of fact if u multiply any of the equations via (-a million) until now including, you will have the means to remedy it via addition, which would be especially plenty the comparable as "removing" y.

That's confusing, you only need to equations two answer a two-variable simultaneous equation and the use of the word negative is not making sense. Do you mean:
y=2x+3
y=-5x
y=-(2.5-1.5)

If y=2x + 3 and y=5x
Then 2x + 3 = 5x
-2x -2x
3 = 3x
x = 1
Hope this helps. Good luck with homework.

I'm not doing your algebra homework for you, but plug in the numbers into the equation. Use order of operations; y= (2x) + 3.
-5x=2x+3

What are you talking about? You have Y equaling everthing under the sun! This is not a math problem, you have a problem with math.

answer is 25

that makes no since what kind of math are you taking if y=5x then it would be unsolveable
