4x - y = -4
5x = 2y +1
how do I solve this using elimination?

x=-3, y=-8

Step-by-step explanation:

you will leave the first equation alone for now

the second, we will subtract 2y from both sides

5x-2y=1

now you system is

4x-y=-4

5x-2y=1

we will multiply the first equation with -2

-8x+2y=8

5x-2y=1

add both equations, we get -8x+5x=9,  -3x=9,  

x=-3

we will replace x with -3 in any equation, lets use 4x-y=-4,

-12-y= -4,         -y=12-4,                -y=8,         y=-8

whats the

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
