Question

On solutions of simultaneous linear equations
Solve the following simultaneous equations.

3x - 4y = 10
4x+3y=5​

Answer 1

Step-by-step explanation:

3x - 4y = 10 ..... (i)

4x + 3y = 5 ......(ii)

(i) *3 is subtracted from (ii) *4

9x - 12y = 30

+ 16x +12y = 20

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

25x = 50

x = 2

therefore, replacing value of x in (ii), we get

8 + 3y =5

3y = -3

y = -1

please mark me brainliest :)
