1) The expressions are not equivalent. When you expand and multiply 2(x + 3) it becomes 2x + 6. This is not equal to 3x + 5

2) They are equivalent. Again, expand and multiply the second expression. 2(3n + 4) becomes 6n + 8. This makes both sides equal.

3) They are equivalent. In the parentheses, you are adding 3 y's and a 2. This gives you 3y + 2. Now add the additional 3y that follows the closed parentheses. You'll have 6y + 2. Now both sides are equivalent.

{ x + y = -2<br> { x - y = -8
g100num [7]

Answer:

(-5, 3)

Step-by-step explanation:

Elimination seems like the best method to use here.

x+y=-2

x-y=-8

---------

2x=-10

Divide everything by two

x=-5

Now plug it back into one of the original equations,

-5+y=-2

Add 5 to everything

y=3

Due tomorrow Please help!!
anastassius [24]

Answer:

A

\frac{1}{8} = \frac{b}{4^{2} }

b = \frac{1}{8} × 4^{2}

b = \frac{4^{2} }{8}

then b = \frac{c^{2} }{a} that is ORANGE

B

-2 - v = -7

v = -7 +2

then v = k + m that is BROWN

C

\frac{14}{q} = \frac{-7}{-4}

q = \frac{14 * -4 }{-7}

then q = \frac{ps}{r} that is YELLOW

D

4m + 2(n) = 5 (n)

4m = 5 (n) - 2n

4m = 3n

m = \frac{3n}{4}

then m =  \frac{3n}{4} that is RED

E

-8 = \frac{x}{-5} - 6

\frac{x}{-5} = -8 + 6

x = -5 (-8 + 6)

then x = y( w + z ) that is LIGHT GREEN
