Question

To the nearest tenth the value of x that satisfies 2x = −2x + 11 is

Answer 1

Answer:

2.8 (from 2.75 because of rounding)

Step-by-step explanation:

2x = -2x + 11

Add 2x on both sides

4x = 11

Divide 4 on both sides

x = 11/4

x = 2.75

Round to nearest tenth

x is about 2.8

Please mark me for brainliest :D !! Thanks!

Answer 2

Answer:

x = 2.8

Step-by-step explanation:

2x = - 2x + 11                       Add 2x to both sides.

2x+2x = -2x+2x + 11           Combine

4x = 11                                 Divide by 4

4x/4 = 11/4

x = 2 3/4

x = 2.75

Rounded to the 10th place, you would get 2.8
