Question

24. Find the value of x and y if:
a) (x - 5, 8) = (6, 8)
b) (4, 3y - 7) = (4. 11)​

Answer 1

Answer:

...............................

Answer 2

$\rm{(x - 5, 8) = (6, 8)}$

• On Comparing This, We Get

$\to\rm{x - 5 = 6, \:8=8}$

• On Eliminating 8 = 8

$\to\rm{x - 5 = 6}$

• Adding 5 to Both Sides

$\to\rm{x - 5 + 5 = 6+5}$

• Simplify

$\to\rm{x= 11}$

$\rm{(4, 3y - 7) = (4, 11)}$

• On Comparing This, We Get

$\to\rm{4= 4, \:3y - 7=11}$

• On Eliminating 4 = 4

$\to\rm{3y - 7=11}$

• Adding 7 to Both Sides

$\to\rm{3y - 7+7=11+7}$

• Simplify

$\to\rm{3y=18}$

• Dividing both Sides by 3

$\to\rm{3y/3=18/3}$

• Simplify

$\to\rm{y=6}$
