Answer 2

▶ Question :-

→ solve : x + 4y = 16, 2x - 3y = 1​ .

▶ Answer :-

→ x = 52/11 , y = 31/11 .


▶ Step-by-step explanation :-


We have,

°•° x + 4y = 16 ........ (1) .

And,

°•° 2x - 3y = 1 ........... (2) .


▶ Solving by elimination method :)

→ Multiply equation (1) by 2 and equation (2) by 1 .

We get,

°•° 2x + 8y = 32 ........ (3) .

And,

°•° 2x - 3y = 1 ..........(4) .


▶ Now, substrate in equation (3) and (4) , we get

2x + 8y = 32 .
2x - 3y = 1 .
- + -
__________

==> 11y = 31 .

•°• y = $\frac{31}{11} .$


▶ Putting the value of y in equation (1) , we get

==> x + 4 × 31/11 = 16.

==> x + 124/11 = 16 .

==> 11x + 124 = 16 × 11 .

==> 11x = 176 - 124 .

•°• x = $\frac{52}{11} .$


✔✔ Hence, it is solved ✅✅.
