To do this, you need to solve either one of the equations for y or x. I'm going to solve for y in the first equation:

6x + 3y = 9

Subtract 6x from both sides:

3y = 9 - 6x

Divide both sides by 3:

y = 3 - 2x

Now that you know what y is equal to, you can substitute it into the second equation:

2x + 3y = 1

2x + 3(3-2x) = 1

Distribute the 3:

2x + 9 - 6x = 1

Combine like terms:

9 - 4x = 1

Subtract 9 from both sides:

-4x = -8

Divide by -4:

x = 2

No substitute this 2 into either one of the equations to get y. I'm going to use the first:

6x + 3y = 9

6(2) + 3y = 9

12 + 3y = 9

Subtract the 12 from both sides:

3y = -3

Divide by 3:

y = -1

ANSWER:

x = 2

y = -1

You can always check by substituting the values into the equations.

Answer:

y = (5-2x)/7 = 5/7 - 2x/7. option C

Step-by-step explanation:

here's your solution

=> 7y + 2x = 5

=> 7y = 5 - 2x

=> y = (5-2x)/7

1- Solution using graphs:
Take a look at the attached images.
The red graph represents the first given function while the blue graph represents the second given function.
We can note that the two graphs are the same line (they overlap).
This means that any chosen point on one of them will satisfy the other.
This means that there are infinite number of solutions to these two equations.

2- Solution using substitution:
The first given equation is:
y = -5x + 3 ...........> equation I
The second given equation is:
2y + 10x = 6 ...........> equation II

Substitute with I in II and solve as follows:
2(-5x+3) + 10x = 6
-10x + 6 + 10x = 6
0 = 0
This means that there are infinitely many solutions to the given system of equations.

Hope this helps :)
