Solve for x:(a) 4x - 21 = 5 - 9x​

Mathematics
1 answer:
lisabon 2012 [21]3 years ago
3 0

Answer:

X = 2

Step-by-step explanation:

First we'll need to simplify this equation:

Add 9x on both sides:

13x - 21 = 5

Add 21 on both sides:

13x = 26

Divide 26/13

26/13 = 2

X=2

(You can check this yourself by plugging x into the equation)
