8 5x=-2 whats the value of the variable?
wlad13 [49]
In order to get the value of x you have to set x by itself subtract from both sides because the only way to get rid of a positve its with a negative now you have 5x=6, now divide 5 from both sides because the only way to get rid of a multiplication is with a division, this will give you the final answer of x=6/5

Hope this helps

Solve the system of equations below x-2y=3 <br><br> 2y-3y=9
Crank
First you solve 2y-3y=9.
2y - 3y = 9 \\ subtract \: 2y \: and \: 3y \\  - y = 9 \\  divide \: by \:  - 1 \\ y =  - 9
Now that you have y, then you substitute y into x-2y=3 to find X

x - 2( - 9) = 3 \\ multiply \:  - 9 \times  - 2 \\ x + 18 = 3 \\ subtract \: 18 \: on \: both \: sides \\ x =  - 15
Your solution is (-15, -9)
