Answer:

Step-by-step explanation:

plug in y and x, if you want to be sure of each answer

In the case of A) here are the 2 equations, y-2=x+4 and 3x+4=x+6

now plug in what a describes

x=1, y=7

7-2=1+4 and 7=7

Therefore the answer is A

Demarco wrote two correct variable expressions to represent the phrase “the product of a number and 7.” Which of these variable

enot [183]

A and b because the "product" is the answer to multiplication, and those are the only answers where 7 and n are being multiplied. Answer b is technically more correct than a is because the coefficient should come before the variable.

9x-y=5 7x-6y=5 Solve the system by the substitution method

qwelly [4]

9x - y = 5
7x - 6y = 5

Solve both equations for one variable. I'll solve for y.

9x - y = 5 Subtract 9x from both sides
-y = -9x + 5 Divide both sides by -1
y = 9x - 5

7x - 6y = 5 Subtract 7x from both sides
-6y = -7x + 5 Divide both sides by -6
y = $\frac{7}{6}$ x - $\frac{5}{6}$

Since both equations equal y, you can set them equal to each other and solve for x.

9x - 5 = $\frac{7}{6}$ x - $\frac{5}{6}$ Multiply both sides by 6 to eliminate the fractions
54x - 30 = 7x - 5 Subtract 7x from both sides
47x - 30 = -5 Add 30 to both sides
47x = 25 Divide both sides by 47
x = $\frac{25}{47}$

Now, plug that x-value into the x of either equation. I'll plug it into 9x - y = 5.

9x - y = 5 Plug in the x-value
9( $\frac{25}{47}$ ) - y = 5 Multiply
 $\frac{225}{47}$ - y = 5 Subtract $\frac{225}{47}$ from both sides
-y = 0.21276595744 (I had to convert it to a decimal) Divide both sides by -1
y = -0.21276595744

So, the answer to the system is (0.53191489361, -0.21276595744)
