Question

can someone please help me answer this question?
I will become a fan and will give a medal!
Question~
Solve the systems using the substitution method.
y = (2/3)x + 1
y + x = 6

Answer 1

so all you have to figure out is what is the value of x which will show the value of y

Answer 2

ok, could you shoe me how to do that? Please?

Answer 3

Just keep trying equations that add up to 6.

Kind of like 3+3

Answer 4

I don't really understand what you mean...

Answer 5

yeah the answer is 3

because \[(2\div3)\times3+1 = 3\]

Answer 6

Basicly replace x with 3

Then the answer shows that y is three

And when you add those together it's 6 ^-^

Answer 7

so the x and y value is 3

Answer 8

Oh ok, Can I show you the example from my lesson and we can try to figure it out using those steps? because I have to show my steps...

Answer 9

Yeah

Answer 10

Method 2 Substitution
Example 2: Solve the following system of linear equations by graphing.
2x - 3y = -2
4x + y = 8
Solution:
S1 Solve one equation for either variable.
Choose the second equation since y is by itself:
y = 8-4x
S2 In the other equation, replace the variable from S1 with what it equaled.
2x - 3(8-4x) = -2
S3 Solve the equation in S2 for the other variable.
14x = -2 + 24 -- x = 22/14 = 11/7
S4 Substitute the value found in S3 into equation in S1.
y = 8 - 4(11/7)
S5 Solve the equation in S4.
y = 8 – (44/7) -- y = 12/7
S6 Write your answer as an ordered pair (x, y).
(11/7, 12/7)

Answer 11

thats the example from the lesson

Answer 12

yeah just use those steps

Answer 13

umm ok
