GIVING BRAINLIEST TO FIRST COMPLETE ANSWER

Mathematics
1 answer:
inn [45]3 years ago
8 0

Answer:

x = -1.4

Step-by-step explanation:

-3(x + 4) = 2x - 5

-3x + (-3*4) = 2x - 5

The mistake was in the above equation where -3 should be multiplied with 4.

-3x -12 = 2x -5

5 -12 = 2x+3x

-7 = 5x

x = -7/5 = - 1.4
