What is the answer x + 2x + 3(x + 4) = 5x - 6

Mathematics
1 answer:
dybincka [34]3 years ago
5 0

Answer:

x= -18

Step-by-step explanation:

x + 2x + 3(x + 4) = 5x-6

Distribute

x+2x+3x+12 = 5x-6

Combine like terms

6x +12 = 5x-6

Subtract 5x from each side

6x+12 -5x= 5x-6-5x

x+12 = -6

Subtract 12 from each side

x+12-12 = -6-12

x= -18
