Distribute:
Subtract 2x on both sides:
Subtract 30 on both sides:
Divide both sides by 3:
Problem 2:
Clear the fraction by multiplying both sides by 5:
Distribute:
Subtract 5x on both sides:
Add 3 on both sides:
Divide both sides by 5:
For this case we must solve the following equation:
Multiplying by 5 on both sides we have:
We add 3 to both sides of the equation:
Subtracting 5x on both sides:
Dividing between -3 on both sides:
