Question

Solve for x: 1.1x + 1.2x - 5.4 = -10

A) x = 5
B) x = -6
C) x = -4
D) x = 4

Answer 1

To solve the equation 1.1x + 1.2x - 5.4 = -10 for x, combine like terms and isolate the x term by adding and subtracting terms.

Step-by-step explanation:

To solve for x, we will simplify the equation by combining like terms. We have 1.1x + 1.2x - 5.4 = -10. Combining the x terms gives us 2.3x - 5.4 = -10. Next, we will isolate the x term by adding 5.4 to both sides of the equation, resulting in 2.3x = -4.6. Finally, we divide both sides by 2.3 to solve for x, giving us x = -2.
