Question

15) Solve the following equations x+y
= 7 and 3x-2y = 11 *
O A) x = 5 and y = 2
O B) x = 5 and y = -2
C) x = -5 and y = -2
D) x = -5 and y = 2 2​

Answer 1

Answer:

what are is the equations to be done.

Answer 2

Answer:

Option A

Step-by-step explanation:

Given: x+y = 7 ......(1)

3x-2y = 11 ......(2)

Equation (1)×2 + Equation (2)

2x+2y+3x-2y= 7×2+11

$5x = 14 + 11$

$5x = 25$

$x = \frac{25}{5}$

$x = 5$

Put the value of x in equation (1)

$5 + y = 7$

$y = 7 - 5$

$y = 2$
