Question

Q10. Solve 2x - 3 = 12(x)2 - 2x + 21​

Answer 1

Answer:

Step-by-step explanation:

2x - 3 = 12(x) 2 - 2x +21

2x - 3 = 24x - 2x +21

2x - 3 = 22x +21

-3 - 21 = 22x -2x

-24 = 20 x

x =  $\frac{-24}{20}$

therefore, x = $\frac{-6}{5}$

Answer 2

Answer:

x = - 1.2

Step-by-step explanation:

2x - 3 = 24x - 2x +21

2x-24x+2x = 21 +3

2x-22x = 24

-20x = 24

x = 24/-20

x = -1.2
