A) x * y = 12
B) x + y = -7
A) x = 12 / y
Substitute this into B
B) 12/y + y = -7
multiplying both sides by "y"
12 + y^2 = -7y
y^2 + 7y + 12 = 0
y = -4
and from equation B we calculate x as -3

Solve 4|x + 6| = 16
Galina-37 [17]

4 | x + 6 | = 16

Divide both sides by 4.

\bf{\dfrac{4|x+6|}{4}=\dfrac{16}{4}   }

\bf{|x+6|=4 }

Absolute value is solved.

\bf{|x+6|=4 }

We know either x + 6 = 4 or x + 6 = -4.

<u>                                                                        </u>

x + 6 = 4 (Possibility 1)

x + 6 - 6 = 4 - 6 (Subtract 6 from both sides)

x=−2

<u>                                                                        </u>

x + 6 = -4 (Possibility 2)

x + 6 - 6 = -4 - 6 (Subtract 6 from both sides)

x=-10

Solution:

x=−2 or x=−10

Liula [17]
M + l = 13 [m = 13 - l]

8m + 10l = 108

8(13 - l) + 10l = 108
104 - 8l + 10l = 108
2l = 4
L = 2

M = 13 - 2 = 11

There are two large pizzas and eleven medium pizzas.
