Answer:

x = -2 y = -4

Step-by-step explanation:

3x- 2y = 2 -> 15x - 10y = 10

5x - 5y = 10 -> 15x - 15y = 30

Substract one equation from another:

15x - 15x - 10y + 15y = 10 -30

5y = -20

y = -4

Plug in y into an equation

3x + 8 = 2

3x = - 6

x = - 2

RSB [31]

Answer:

z = 66

Step-by-step explanation:

QT is a midsegment. Thus, applying the midsegment theorem:

RS = 2(QT)

QT = z - 33,

RS = z

Plug in the values into the equation

z = 2(z - 33)

z = 2z - 66

Subtract 2z from each side

z - 2z = -66

-z = -66

Divide both sides by -1

z = 66
