Solve, using the substitution method.
galben [10]
Y – 3x = 7
y -3x +3x = 7+3x
y = 7+3x

21 + 9x = 3y
21 + 9x = 3(7+3x)
21 + 9x = 21 + 9x

The answer is  B.There are an infinite number of solutions.

Y = 7x + 9<br> 2y + 2x = -18
zvonat [6]

Answer:

Step-by-step explanation:

Just multiply the first equation by -1 and then add them together to find x. Should look something like

-2x - y = -7

5x + y = 9

--------------------

3x + 0 = 2

x = 2/3

Now back substitute using either equation to find y. I'll use the first:

2(2/3) + y = 7

4/3 + y = 7

y = 7 - 4/3 = 21/3 - 4/3 = 17/3

Answer:

x=2/3

y=17/3
