Answer:

The first problem.

Step-by-step explanation:

-6 + (-6) + (-6) = -18

first problem: 3 · (-6) = -18

second problem: 6 · (-6) = -36

third problem: -3 · (-6) = 18

fourth problem: -6 · (-6) = 36

Therefore, the first problem is equivalent because it had the same answer as the original problem.

Answer:

x = -2, proven below.

Step-by-step explanation:

3x + 7 + 2(4x+1) = 3(x-1) - 4

I need it step by step

elena-s [515]

Answer:

Step-by-step explanation:

we want y by itself...sooo

y - 19 = - $\frac{6}{10}$ (x - (-5))

y - 19 = - $\frac{6}{10}$ (x+5)

y - 19 = - $\frac{6}{10}$ x - $\frac{6}{2}$

y = - $\frac{6}{10}$ x - 3 +19

y = - $\frac{6}{10}$ x + 16
