2x + y = 8 find four solutions

see explanation

Step-by-step explanation:

Choose any value for x, substitute into the equation and solve for y, that is

x = - 1

2(- 1) + y = 8

- 2 + y = 8 ( add 2 to both sides )

y = 10

x = 0

2(0) + y = 8

0 + y = 8

y = 8

x = 1

2(1) + y = 8

2 + y = 8 ( subtract 2 from both sides )

y = 6

x = 3

2(3) + y = 8

6 + y = 8 ( subtract 6 from both sides )

y = 2

4 possible solutions are (- 1, 10 ), (0, 8 ), (1, 6 ) and (3, 2 )

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation

the answer is 150.6

step-by-step explanation:

you multiply .02 by 30 and get .6.

and then you multiply 5.00 by 30 and get 150.

hope this !
