Question

iii) Evaluate: y/2 + y/7 = 9

Answer 1

$\frac{y}{2}+ \frac{y}{7} = 9$

Take LCM

$\frac{7y+2y}{14} = 9$

Transpose 14 to RHS

$7y+2y = 126$

$9y = 126$

$y = \frac{126}{9} \\ = 14$

∴Answer is 14

Answer 2

Answer:

y= 14

Step-by-step explanation:

7y+2y /14 = 9

9y = 9×14

9y = 126

y= 126/9

y= 14
