Question

solve the following simultaneous equations 3 x minus 4 Y is equal to 10 and 4 x + 3 Y is equal to 5

Answer 1

Answer:

Step-by-step explanation:

Answer 2

GIVEN  EQUATIONS

3x-4y = 10 ------------------eqn 1

4x+3y = 5 ----------------------eqn2

use elimination method i.e, multiply both eqn with the coefficients of either x ot y of each other

(3x-4y = 10) * 3

(4x+3y = 5) * 4

9x -12y = 30

16x+12y = 20

_______________

25x = 50

∴ x = 2

put the value of x in the eqn 1

3*2-4y=10

6 - 10 = 4y

∴ y= -1

you can check the answer by putting the values in the given equations
