(X+2) + 3 = 10 X + 1
HOW TO DO THIS ?

MATH 
Leonardo,
First, take off the parentheses in the left equation:
x+2+3=10x+1
After that, calculate the numbers in the left equation:
x+5=10x+1
You need to group the number with number, so we can subtract both sides with 5:
x+55=10x+15
x=10x4
After that, you can group the variable with variable, so we need to subtract both sides with 10x
x10x=10x10x4
9x=4
Finally, we get x=4/9
