6(x + 3) = 3x - 3 Given
6x + 18 = 3x - 3 Distribute the 6
6x = 3x - 21 Subtract 18 from both sides
3x = - 21 Subtract 3x from both sides
x = -7 Divide both sides by 3

5x - 2 = 3(x + 2)
5x - 2 = 3x + 6
5x = 3x + 8
2x = 8
x = 4

Jeff's solution is incorrect; his solution is incorrect because he added 3x to the left side when he should have subtracted it to cancel it from the right side.

Hope this helps.

What is the value of f(x) = 2 • 2^x for f(–2)? Will Give brainliest answer!!!

Sedbober [7]

For f(-2), x will equal -2.

Plug the x-value into the equation:

$2 \times 2^{-2}$

A negative exponent means that the term turns into a fraction, with 1 as the numerator and the positive exponent as the denominator.
Solve 2^(-2):

$2^{-2} = \frac{1}{2^{2}} = \frac{1}{4}$

Solve the problem:

$2 \times \frac{1}{4} = \frac{1}{2}$

f(-2) will equal 1/2.

carmen recovered 2 gold bars that were stolen from a safe. the first bar weighed 2 2\5 pounds. the second bar weighed 1 2\3 time

TiliK225 [7]

What you do is 2 2/5 times 1 2/3
Change them to improper fractions will be:
12/5 Times 5/3

You will get:
60/15

That would make you :
4 pounds if you simplify it

She recovered 4 pounds of gold!
