Question

3w - 4z = 8
2w + 3z = -6

Answer 1

Answer:

3w - 4z = 8

2w + 3z = -6

w=0 and z=2

Answer 2

Answer:

w= 0

z= -2

Step-by-step explanation:

3w-4z= 8 --------(i)

2w+3z= -6 --------(ii)

Multiply equation (i) by 3 and equation (ii) by 4 and then add equation (i) and (ii)

9w-12z+8w+12z= 24+(-24)

17w= 24-24

17w= 0

w=0

Putting w=0 in equation (i)

3(0)-4z= 8

-4z= 8

z= -2

Hope It Helps :)
