13x + 15= 11x - 25
13x + 15= 11x - 25
13x - 11x = -15 + (-25)
2x = -40
x = ?
the answer is -10 according to the back of my book.. but idk how to get that..
Please ask your teacher which answer is right.
To solve this equation, you need to isolate the variable x on one side of the equation. Here's how you can do it step by step:
1. Start by moving all the terms containing x to one side of the equation. In this case, subtract 11x from both sides:
13x + 15 - 11x = 11x - 25 - 11x
After simplifying, you have:
2x + 15 = -25
2. Next, isolate the constant term on the other side of the equation by subtracting 15 from both sides:
2x + 15 - 15 = -25 - 15
After simplifying, you have:
2x = -40
3. To solve for x, divide both sides of the equation by 2:
(2x)/2 = (-40)/2
After simplifying, you get:
x = -20
Therefore, the solution to the equation 13x + 15 = 11x - 25 is x = -20.
