Question

one
Ex. (2) Solve : 3x + 2y
= 29; 5x
y = 18
Solution : 3x + 2y = 29..
(1) and
5x - y = 18 ... (II)
Let's solve the equations by eliminating 'y'. Fill suitably the boxes below.
Multiplying equation (II) by 2.
.. 5x X
- ух = 18 x
... 10x 2y =
(IDI)
Let's add equations (1) and (III)
3x + 2y = 29
х
Substituting x = 5 in equation (1)
3x + 2y = 29
+ 2y = 29
+ 2y = 29
3 O
2y = 29 -
2y =
(x, y) =
iy=1
y 0
is the solution.​
