Question

What is the solution to the equation 5x + 1.2 = -3.8, given the replacement set -1, -0.52, 1?

1) x = -1
2) x = -0.52
3) x = 1
4) Cannot be determined

Answer 1

To solve the equation 5x + 1.2 = -3.8, subtract 1.2 from both sides, divide by 5, and find that x = -1.

Step-by-step explanation:

To solve the equation 5x + 1.2 = -3.8, we need to isolate the variable x. To do this, we can subtract 1.2 from both sides of the equation:

5x = -3.8 - 1.2

5x = -5

Next, we divide both sides of the equation by 5 to solve for x:

x = -5/5

x = -1

Therefore, the solution to the equation is x = -1.
