Add them up i think i never tried this
X= -15
First, we want to combine like terms.
4x-10=20+6x
Subtract 4x from both sides
-10=20+2x
Subtract 20 from both sides
-30=2x
Divide by 2 to isolate the variable
X= -15
10(4x-1) is the answer to your question my friend
A negative times a negative is always a positive so the answer would be positive.
