solve the following simultaneous equations. 1) 4x + 3 y = 18 ;. 3x -2y = 5 ​

Answer 1

Answer:

1) x=2 and y=3 2) x=3 and y=2

Step-by-step explanation:

1) putting the value of x=2 and y=3 in the equation:

(4×3) + (3×2) = 18

12 + 6 =18

18=18

LHS=RHS

2) Similarly,

(3×3) - (2×2)= 5

9 - 4 = 5

5=5

LHS=RHS
