Question

Solve x/3+y/4=4and 5x/6_y/8=4by elimination method

Answer 1

Answer:

x = 6 and y = 8

Step-by-step explanation:

x/3 + y/4 = 4

(4x + 3y)/12 = 4

4x + 3y = 4 × 12

4x + 3y = 48 --------(1)

5x/6 - y/8 = 4

(20x - 3y)/24 = 4

20x - 3y = 24 × 4

20x - 3y = 96 -------(2)

on adding eq 1 and 2

4x + 3y = 48

20x - 3y = 96

24x = 144

x = 144/24

x = 6

put x = 6 in eq 1

4x + 3y = 48

4(6) + 3y = 48

24 + 3y = 48

3y = 48 - 24

3y = 24

y = 24/3

y = 8
