Question

solve the linear pair x minus 4 Y - 42 equal to zero and 5 x minus y minus 13 is equal to zero​

Answer 1

Answer:

yep

Step-by-step explanation:

x - 4y = 14-------------------1

5x - y = 13 ------------------2

Mul by 4 to equation 2 then add

x - 4y= 14

20x - 4y =52

- + -

-----------------

-19x = - 38

-------------------

19x =38

x = 2

value of x put in equation 2

5*2 - y = 13

10 - y = 13

-y = 13 - 10

-y = 3

y = - 3

SO VALUE OF X AND Y ARE 2 & - 3 Respectively
