Question

Solve by elimination method
$3x - 4y = - 15$
$x + y = 2$
​

Answer 1

Answer:

3x - 4y = -15

4(X + y = 2)

3x - 4y = -15

4x + 4y = 8

7x = -7

X = -7/7

X = -1

X + y = 2

-1 + y = 2

y = 2+1

y = 3

Answer 2

3x-4y -15

4(X +y= 2)

3x - 4y -15

4x +4y =8

7x = -7

X= -7/7

X=-1

X+y= 2

-1+y 2

y 2+1

y=3
