4. Tell whether the systems have one solution,
hjlf

Answer:

x= 2,

,y = 5

Step-by-step explanation:

Solve by Substitution :

// Solve equation [1] for the variable y

[1] y = 5x - 5

// Plug this in for variable y in equation [2]

[2] -4x + 2•(5x-5) = 2

[2] 6x = 12

// Solve equation [2] for the variable x

[2] 6x = 12

[2] x = 2

// By now we know this much :

x = 2

y = 5x-5

// Use the x value to solve for y

y = 5(2)-5 = 5

Solution :

{x,y} = {2,5}

Solve for x and y: y=2+7x −2x+6y=172 Select one:
Ymorist [56]

It is pretty easy to eliminate the wrong answers by trying the answers in the equations.

a. 7 times 30 is way more than 4

c. 6 times 226 is way more than 172, even after subtracting 64

d. 7 times -74 is way less than 4

The appropriate choice is

... b. x=4, y=30

You can check it with your graphing calculator.

_____

Since you have an expression for y, you can substitute that into the second equation:

... -2x + 6(2+7x) = 172 . . . . substitute for y

... 40x = 160 . . . . . . . . . . . . eliminate parentheses, subtract 12, collect terms

... x = 4 . . . . . . this is sufficient to help you locate the correct answer
