11x+4y=-46<br> 7x-4y=10 <br> Find x and y
UNO [17]

Answer:x=-2 y=-6

Step-by-step explanation:

11x+4y=-46..........(1)

7x-4y=10..............(11)

Add (1) and (11)

11x+7x+4y-4y=-46+10

18x=-36

Divide both sides by 18

18x/18=-36/18

x=-2

substitute x=-2 in (11)

7x-4y=10

7(-2)-4y=10

-14-4y=10

Collect like terms

4y=-14-10

4y=-24

Divide both sides by 4

4y/4=-24/4

y=-6

In order to find the expression equivalent to our given expression, we have to simplify our given expression :)

-3z + z + 2

**Remember : the "z" and "2" become a positive because a negative times a negative is always a positive!**

Now, add like terms.

(-3z + z) + 2

Simplify.

-2z + 2

Look at our given answer choices.

Our answer is c. -2z + 2
