Question

Solve simultaneous equations by elimination method​

Answer 1

Answer:

y = -2

Step-by-step explanation:

Solve for x in 3/x + 4y=7

x = 3/ 7- 4y

Substituting x= 3/ 7- 4y into

5/x + 6/ y = 13

5 (7- 4y) / 3 + 6y = 13

Solve for y in 5 (7-4y) + 6y = 13

y= - 2

Substituting y= - 2 into

x = 3/ 7- 4y

x = 1/ 5

Therefore x = 1/ 5

y= - 2
