Sagot :
Answer:
-7.5
Step-by-step explanation:
5x+20=x-10
Subtract x from both sides to have the variable on one side of the equation:
4x+20=-10
Subtract 20 from both sides of the equation to isolate the variable:
4x=-30
Divide both sides by 4 to find x:
x=-30/4=-7.5
5x+20=x-10
1. Subtract x from both sides which will give you 4x+20=-10
2. Subtract 20 on each side of the equation which will give you 4x=-30
3. Divide 4 on both sides to leave x by itself and you will get
5x+20=x-10
-x -x
———————
4x+20=-10
-20 -20
———————
4x=-30
4x/4=-30/4
X=-30/4
-30/4 can reduce to -15/2 so x=-15/2
