Question

Solve for x and y using elimination method 10 x + 3 y is equal to 75, 6 x minus 5 y is equal to 11

Answer 1

Step-by-step explanation:

The given equations are

10x + 3y = 75. ....(i)

6x - 5y = 11. ....(ii)

Multiplying (i) by 5 and (ii) by 3, we get

50x + 15y = 375. .... (iii)

18x + 15y = 33. ..... (iv)

Adding both

=> 68x = 408

=> x = 408/68

=> x = 6

Putting x = 6 in (i), we get

=> 10(6) + 3y = 75

=> 60 + 3y = 75

=> 3y = 75 - 60

=> 3y = 15

=> Y = 5

Hence, x = 6 and y = 5
