We want to get x on a side by itself
-5x+4=-21
First subtract 4 from both sides (to get x by itself) the equation is now
-5x=-25
Then to find the value of a single x, divide -25 by -5
-25/-5= 5
x=5
-5x+4=-21
First subtract 4 from both sides (to get x by itself) the equation is now
-5x=-25
Then to find the value of a single x, divide -25 by -5
-25/-5= 5
x=5
