<span>Multiply equation(2) with 4 so that coefficient of become same in both the equations(You can make coefficient of y same and can follow the following procedure.)
</span><span>* Subtract (3) from (1)
* </span>Divide both sides by -19
*Subtract 21 from both sides.
*Divide both sides by 4
so the solution is x= 3 and y= -7
Hope I helped you :)

Answer:
<u>SA = 189 cm^2</u>
Step-by-step explanation:
What you're going to want to do is calculate the surface area of each type of side (triangle or rectangle) then add them up accordingly!
Starting with triangles: area = 1/2 * l * h
So, in this scenario its (1/2) * 6 * 4 , or half of 24, which is 12 cm^2
Since we have two triangular sides, that totals to 24 cm^2.
Then the rectangular sides: area = l*h
so, 5*11 = 55 cm^2
We have three rectangular sides, totalling 165 cm^2
165+24 = 189 cm^2
Answer:
The value of z is 1.
Step-by-step explanation:
Given:
We need to solve the problem using distributive property.
Solution:
For the given equation we will apply distributive property;
By Definition of Distributive property which states that;
"The distributive property lets you multiply a sum by multiplying each addend separately and then add the products."
example = 
So we get;
Now by using Subtraction property we will subtract both side by 1050 we get;
Now Dividing both side by 21 by using Division property we get;
Hence The value of z is 1.
