Solve 42x - 3 = 5x
5 Answers | add yours
The equation 42x - 3 = 5x has to be solved.
42x - 3 = 5x
Subtract 5x from both the sides
=> 42x - 5x - 3 = 5x - 5x
=> 37x - 3 = 0
Add 3 to both the sides
=> 37x = 3
Divide both sides by 37
=> x = 3/37
The solution of the equation is x = `3/37`

To solve for x, you first have to put x to one side, and the constants on the other side of the equation. Then, you divide the constant by the coefficient of x.
42x -3 = 5x
42x - 5x - 3 = 0 (-5x on both sides)
42x - 5x = 3 (+3 on both sides)
37x = 3 (then, divide the 3 by the coefficient of x, 37)
x = 3/37 :)

First you should add 3
Then minus by 5x
Finally divide by 37x so your answer is 3/37 or in decimals the answer is: 0.0810810810810811

42x - 3 = 5x
add 3 to both sides: 42x - 3 + 3 = 5x + 3
simplify: 42x = 5x + 3
subtract 5x from both sides: 42x - 5x = 5x + 3 - 5x
simplify: 37x = 3
divide both sides by 37: 37x/37 = 3/37
simplify: x = 3/37 or 0.08...
