Ways of solving it
Step-by-step explanation:
20x - 5x = 65 - 5
as the numbers cross over the equality sign, their positive changes to negative and vice versa
15x = 60
Divide both side by the coefficient of X which is the number Infront of X
15x/15 = 60/15
X=4
OR
20x + 5 = 5x + 65
Dividing through by 5. All the numbers above are divisible by 5. 5 is also the LCM
4x + 1 = X + 13
4x - X = 13 - 1
3X = 12
X = 4
