Lesson Steps

Step	Type	Explanation	Answer
1	Problem	Solve the linear equation for x: \$ x/5 + (x+2)/5 = 1/5 \$

Answer

Problem

Solve the linear equation for x:
\$ x/5 + (x+2)/5 = 1/5 \$

Step

Taking LCM as 5

\$ (x + x + 2)/5 = 1/5 \$

Step

Adding "x" variables

\$ (2 x + 2)/\cancel5 = 1/\cancel5 \$

Step

After cancelling denomenators we get

2 x + 2 = 1

Step

Adding "-2" on both we get

\$ 2 x + \cancel2 - \cancel2 = 1 - 2 \$

Step

After cancellation we get

2 x = -1

Step

Dividing on both sides by "2" we get

\$ \cancel(2)/\cancel(2)x = -1/2 \$

Step

After cancellation we get

x = - 1/2
