Question

find unique saolution for k for equations 2x+k=1 and 3x-5y=7

Answer 1

Answer:

2/3=k/-5

3k=-10

K=-10/3

Step-by-step explanation:

Answer 2

Answer:

-(11+10y)/3

Step-by-step explanation:

2nd equation:

3x-5y = 7

3x = 7+5y

x = (7+5y)/3

First equation:

2x+k = 1

k = 1-2x

= 1 - 2(7+5y)/3

= (3-14-10y)/3

= (-11-10y)/3

= -(11+10y)/3
