Answer:

The solution set is (5,6).

Step-by-step explanation:

Given equations are:

-6x + 6y= 6 Eqn 1

-6x + 3y=-12 Eqn 2

Subtracting Eqn 2 from Eqn 1

(-6x+6y)-(-6x+3y)= 6-(-12)

-6x+6y+6x-3y=6+12

3y = 18

Dividing both sides by 3

$\frac{3y}{3}=\frac{18}{3}\\y=6$

Putting y=6 in Eqn 1

-6x+6(6)=6

-6x+36=6

-6x=6-36

-6x=-30

$\frac{-6x}{-6}=\frac{-30}{-6}\\x=5$

Hence,

The solution set is (5,6).

Pls help me full steps I needed Find X

zaharov [31]

Answer:

x=60°

Step-by-step explanation:

Let's say the point where angle x is, be K

Because ABCD and PQRS are paralelograms,

∡PSR = ∡PQR =130°

and

∡DAB=∡DCB=70°

and by angles between parallels

∡SPQ + ∡PQR = 180°

∡SPQ + 130° = 180°

∡SPQ = 50°

by angles opposite by vertex

∡PKC = ∡BKQ = x

So in triangle PKC the sum of all angles must add up to 180°

∡SPQ + ∡PKC + ∡DCB = 180

50 + x + 70 = 180

x = 60
