Question

if 2x+1=31-x then find the value of x​

Answer 1

Answer:

2x+1=31-x

2x-x=31-1

x=30

Answer 2

Answer:

Hello mate! Here is your answer...

So the equation given is...

2x+1=31-x

So first the goal is to get all the x's on one side of the equation...

Move the '-x' to LHS of '='(it becomes +x)

2x+1+x=31

Now add all the x's on the LHS of the'='

3x+1=31

Remember , goal is to isolate all the x terms on one side of '='

So move the '+1' to RHS of the '='(it becomes -1)

3x=31-1(30)

3x=30

now to solve for x, since 3 is multiplied by x, so perform the opposite operation (division) to leave only X on LHS of '='

3x/3=30/3(whenever you perform something on one side of equal to symbol, aways remember to do same thing on other side)

X=10

This is your answer!

hope it helps you...
