Answer:
1. x=6 2. x=10 3. x= 4.5 4. x= 24
Step-by-step explanation:
1. Remove the constant in the equation ( the number that don't have letters or are behind the equal sign) by subtracting the number to itself and the sum, then divide the coefficient by the remaining number in the answer (2x divided by 2, 12 divided by 2)
2. Remove the coefficient on both sides again (15), then remove the coefficient again with division (3t)
3. Remove the coefficient on both sides again (5) , then remove the coefficient again with division (4d)
4. This one might be tricky for you, remove the constant once again and after that remove the coefficient by multiplying it by its inverse (opposite, so if you have 1/4 the inverse is 4/1) you multiple the coefficient by the inverse to cancel it out, then do the same with the remaining number of the other side of the equal sign.
Have a nice day
