3(2x-5)= 21<br> solve it 2 different ways <br> plzz hurry i need help
docker41 [41]

Answer:

x = 6

Step-by-step explanation:

3 (2x - 5) = 21

=> 6x - 15 = 21

=> 6x = 21 + 15

=> 6x = 36

=> x = 36 / 6

=> x = 6

OR

3 (2x - 5) = 21

=> 2x - 5 = 21 / 3

=> 2x - 5 = 7

=> 2x = 7 + 5

=> 2x = 12

=> x = 12 / 2

=> x = 6

Hope it helps :)
