Question

2x + y = 8 find four solutions

Answer 1

see explanation

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 )
