Answer:

Yes.

Step-by-step explanation:

Set the equations equal to each other to determine their equality.

-4[3(x - 7)] = 6(14 - 2x)

Distribute the 3 and the 6 into their respective parenthesis.

-4[3x - 21] = 84 - 12x

Distribute the -4 into the brackets.

-12x + 84

Rearrange the equations.

84 - 12x = 84 - 12x

Since the equations come out to be the same thing on both sides so that any value satisfies it, the equations are equivalent.

Answer:

Answer is 28/4 = 7

Step-by-step explanation:

Given

Beth B = 28 problem

B has 4 times more problem than Mery m

Find

Total number of problem Mery m has if Beth has 4 times more problem than Beth

So,

B = 4 x m

m = B/4 = 28/4 = 7

Finally answer (d) is correct which is 28 ÷ 4 = m
