Answer:
x = 1/3
Explanations:
The given equation is:
7x + 4 = 5 + 3x + 1x
Step 1: Collect the like terms
Note that 3x and 1x cross to the left hand side of the equality sign to become -3x and -1x respectively. 4 also crosses to the right hand side of the equality sign to become -4.
The equation then becomes:
7x - 3x - 1x = 5 - 4
3x = 1
Step 2: Divide both sides by 3
3x / 3 = 1 /3
x = 1/3
