The pure hand hopes to adopt to ask to give a cent
17x-12.5x = 144-17x-14.5x to solve the equation
17x-12.5x=144-17x-14.5x
4.5x+31.5x=144
36x=144
x=4
5x + 12 = a to solve the equation
5x + 12 = a to solve the equation
5x = a -12
x = a/5 - 12/5
The solution equation is 7 × (x + 6) - 20 = 100 + 5x
What's the formula
7*(x+6)-20=100+5x
7x+42-20=100+5x
7x+22=100+5x
7x-5x=100-22
2x=78
x=39
