Question

(xiii) 9(6 - x)-36 = 9(6 + x)​

Answer 1

Step-by-step explanation:

$54 - 9x - 36 = 54 + 9x$

$- 9x - 9x = 54 + 36 - 54$

$- 18x = 90 - 54$

$- 18x = 36$

$- x = \frac{36}{18}$

X = -2

Answer 2

Answer:

x = 4

Step-by-step explanation:

= 9(6 - x)-36 = 9(6 + x)

= 54-9x-36 = 54+9x

= 18-9x = 54+9x

= 18+54 = 9x+9x

= 72 = 18x

x = 72/18

x = 4
