How to solve the equation (5x + 1) × (4x + 1) - 5x × 4x = 38 + 53

How to solve the equation (5x + 1) × (4x + 1) - 5x × 4x = 38 + 53


The equation is expanded as follows: 20x & # 178; + 9x + 1-20x & # 178; = 91
It is reduced to 9x + 1 = 91
9X=90
X=10
Therefore, the equation is x = 10



4x+7=5x-2


4x+7=5x-2
7+2=5x-4x
x=9



How to solve 4x-7 + 5x = 3.8


9X-7=3.8
9X=10.8
X=1.2



Solution equation: X-2 + 0.4x/0.6 = 1 - (0.5x-1) / 0.5


Hello
x-2+0.4x/0.6=1-(0.5x-1)/0.5
x-2+2/3x=1-x+2
5/3x-2=3-x
5/3x-x=2+3
8/3x=5
x=5÷8/3
x=15/8
