Solve: 8.5x +8 = 1.3x + 15
A. x = 50.4
B. x = 0.7
C. x = 3.2
D. x = 1.0
Is B the correct answer
To solve this equation, we need to isolate the variable x. Here's how we can do it step by step:
1. Start by subtracting 1.3x from both sides to get rid of the x term on the right side of the equation:
8.5x + 8 - 1.3x = 15
Simplifying the left side gives us:
7.2x + 8 = 15
2. Next, subtract 8 from both sides to isolate the variable x:
7.2x = 15 - 8
Simplifying the right side gives us:
7.2x = 7
3. Finally, divide both sides of the equation by 7.2 to solve for x:
x = 7/7.2
Evaluating the right side of the equation gives us:
x ≈ 0.972
Therefore, the correct answer is not B. The correct answer is approximately x = 0.972, which is not listed among the options.
No.
8.5x +8 = 1.3x + 15
7.2x = 7
