Question
Solve the equation:
-5x = 25
- x = 20
- x = -20
- x = -5
- x = 5
Hint:
Here we have to solve the equation which is given is -5x = 25. This equation is just a linear equation. Use the method to solve the linear equation.
The correct answer is: x = -5
Here we have to solve this equation,
Firstly, we have given the equation is
-5x = 25 --(1)
Multiply both sides by -1, we have,
5x = -25
Divide both side by 5,
5x/5 = -25/5
x = -5
Therefore the solution of the equation is x = -5.
The correct answer is x = -5.
In this question, we have to solve the equation, basically we have to find the value of x. And it is linear equation that’s why it contain only one variable so its easy to find the value of x.
