Question

Solve the simultaneous equations

x + 11y = 1 ; 3x + 4y = 10
​

Answer 1

Answer:

x + 11y = 1 ------(1)

3x + 4y =10-----(2)

x =1 - 11y------(3)

value of x put in (2)

3(1 - 11y) + 4y = 10

3 - 33y +4y = 10

-29y = 7

y = 7/-29

Step-by-step explanation:

value of y put in (3)

x = 1 - 11.7/-29

= 1 +77/29

= 106/29

Answer 2

Answer:

3x +33y = 3

3x + 4y = 10

- -. -

__________

29y = -7

y = -7/29

x - 11*7/29 = 1

x - 77/29 = 1

x = 1 + 77/29

x= 29+77/ 29

x= 106/29
