4) -3(4x + 1) - 8x = -16 - 7x
how would i do this?

You need to get x by itself

(x = 1)

Step-by-step explanation:

1. Expand.

-12x - 3 - 8x = - 16 - 7x

2. Simplify

-20x - 3 = -16 - 7x

3. Add 20x to both sides.

-3 = -16 -7x + 20x

4. Simplify.

-3 = -16 + 13x

5. Regroup terms.

-3 = 13x - 16

6. Add 16 to both sides.

-3 + 16 = 13x

7. Simplify.

13 = 13x

8. Divide both sides by 13.

1 = x

9. Switch sides

x = 1

$30.32

step-by-step explanation:

65.00*.12=2.80

65.00-2.80=57.20

57.20*1.06=60.632

60.632/2=30.316

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
