X+y=0 2x-3y=5 solve suing elimination method

x = 1 and y= -1

Step-by-step explanation:

Firstly, uoi need to make sure one value in front of either both y's or both x's are the same. Lets make the two x's the same.

Multiply the first simultaneous equation by -2:

-2x - 2y = 0

2x - 3y = 5

Add the two:

-2x + 2x = 0

-2y + -3y = -5y

0 + 5 = 5

5y = -5

So y = -1

Substitute all values of y with -1 in the second equation:

2x - 3(-1) = 5

2x - -3 = 5

2x + 3 = 5

2x = 5 - 3

2x = 2

x = 1

So x = 1 and y= -1

45

step-by-step explanation:

to find a percentage, add a decimal in front and multiply it by the other number.

.25 times 180= 45

yes   because as the functions are graphed they eventually will intersect unless otherwise
