May someone give me an example on how to do this "-5x+4=-4x+15"?
Combine terms by adding 5x and subtracting 15 from both sides.
-11 = 9x
Divide both sides by 9.
-11/9 = x
Thank you I get it now, do you have any examples for this one "-3x+1=-2x-3"?
wait never mind sorry i got it!
How do you get 5 and 15 though?
Since you have -5x on one side, to combine it with the 4x on the other side, you add 5x to both sides. This cancels out the -5x on one side and adds 5x to 4x on the other.
The same principle works with the 15.
To solve the equation "-5x + 4 = -4x + 15," you can follow these steps:
Step 1: Simplify the equation by combining like terms on both sides.
Start with the equation "-5x + 4 = -4x + 15."
Combine the x terms on both sides:
-5x + 4x + 4 = -4x + 4x + 15.
This simplifies to:
-x + 4 = 15.
Step 2: Isolate the x term on one side of the equation.
To do this, subtract 4 from both sides of the equation:
-x + 4 - 4 = 15 - 4.
This simplifies to:
-x = 11.
Step 3: Solve for x by multiplying both sides of the equation by -1 to cancel out the negative sign in front of x.
Multiply both sides by -1:
(-1)(-x) = (-1)(11).
This simplifies to:
x = -11.
So, the solution to the equation "-5x + 4 = -4x + 15" is x = -11.
