Solve the
9x+42=4x-13
The solution is x=
2 answers:
You isolate the x term basically.
First you bring 4x from the right hand side to the left hand side and so the equation would be: 9x - 4x + 42 = -13
Then you bring 42 from the left hand side to the right hand side so the equation would look something like this: 9x - 4x = -13 - 42
Next subtract the x terms and the numbers on the right hand side too so you get: 5x = -55
Remove the coefficient from x and bring it to the right hand side with the operation as division. So you get: x = -55/5
Solve the division and you get: x = -11

Answer:
x = -11
Step-by-step explanation:
9x+42=4x-13
(add 13 to both sides)
9x+55=4x
(subtract 9x from both sides)
55=-5x
(divide by -5)
-11 = x
