Use the substitution method to solve the system of equations. Choose the

Hatshy [7]

Answer:

(3, 2) is the ordered pair for the given system of equations.

Step-by-step explanation:

Given:

2 x+ y = 8.......................(i)

y = - x + 5........................(ii)

Put y = - x + 5 in equation (i)-

2 x + ( - x+ 5) = 8

2 x - x + 5 = 8

x = 8 - 5

x = 3

Now put x = 3 in equation (ii)-

y = - 3 + 5

y = 2

Hence the (3, 2) is the correct ordered pair.

I just need help with three, four, and seven. Solve the system of linear equations, and determine if the equation has one soluti

likoan [24]

3. If $y=5x+9$ and $y=3x-2$ , then

$5x+9=3x-2\implies2x+9=-2\implies2x=-11\implies x=-\dfrac{11}2$

Then

$y=5\left(-\dfrac{11}2\right)+9=-\dfrac{55}2+9=-\dfrac{37}2$

(only one solution)

4. If $y+2=4x$ , then $y=4x-2$ . So we're told that $4x-5=4x-2$ but this is impossible, because that would that for any $x$ , we have -5 = -2. This is false, so this system has no solution.

7. "y is 6 less than 3 times x" means $y=3x-6$ . "x is 2 more than one-third of y" means $x=\dfrac13y+2$ . Solving the second equation for $y$ gives $y=3x-2$ , which would mean $3x-6=3x-2$ . But for the same reason as in (4), there is no solution. For any value of $x$ , this equation gives the false conclusion that -6 = -2.
