To solve the equation 85x = -10, divide both sides of the equation by 85:
85x/85 = -10/85
x = -10/85
So the solution is -10/85, or written as a decimal, approximately -0.1176.
To solve the equation 85x = -10, you need to divide both sides of the equation by 85. This will isolate the variable, x, on one side of the equation.
Dividing both sides by 85 gives:
x = -10/85
This can be simplified by dividing both the numerator and denominator by their greatest common factor, which is 5.
x = -2/17
So, the solution to the equation 85x = -10 is x = -2/17.
To find the solution of the equation 85x = -10, you need to isolate the variable x. In this equation, x is being multiplied by 85, so to isolate x, divide both sides of the equation by 85.
Following these steps:
1. Start with the equation: 85x = -10
2. Divide both sides of the equation by 85: (85x) / 85 = (-10) / 85
3. Simplify the division: x = -10/85
4. The solution to the equation is x = -10/85.
So the answer is option -5/8 which is written as negative Start Fraction 5 over 8 End Fraction.
