What is the solution of the equation - x/2.9 = -3
A. -87
B. 87
C. 8.7
D. -8.7
To find the solution of the equation -x/2.9 = -3, we need to isolate x.
First, multiply both sides of the equation by 2.9 to get rid of the fraction:
2.9 * (-x/2.9) = 2.9 * (-3)
This simplifies to:
-x = -8.7
Next, divide both sides of the equation by -1 to isolate x:
(-x)/(-1) = (-8.7)/(-1)
This simplifies to:
x = 8.7
Therefore, the solution to the equation -x/2.9 = -3 is x = 8.7
The correct answer is C. 8.7
To find the solution of the equation -x/2.9 = -3, you can start by isolating the variable x.
1. Multiply both sides of the equation by 2.9 to eliminate the fraction:
-x/2.9 * 2.9 = -3 * 2.9
Simplifying the left side:
-x = -8.7
2. To isolate x, multiply both sides of the equation by -1:
-1 * (-x) = -1 * (-8.7)
Simplifying:
x = 8.7
The solution to the equation -x/2.9 = -3 is x = 8.7.
Therefore, the correct answer is C. 8.7.
To find the solution of the equation - x/2.9 = -3, we need to isolate the variable x.
First, we can start by multiplying both sides of the equation by 2.9 to eliminate the fraction.
- x/2.9 * 2.9 = -3 * 2.9
This simplifies to:
- x = -8.7
Next, we can multiply both sides of the equation by -1 to get x by itself:
- x * -1 = -8.7 * -1
This simplifies to:
x = 8.7
Therefore, the solution to the equation - x/2.9 = -3 is x = 8.7.
Therefore, the correct answer is C. 8.7.
