Remmeber, you can do anything to an equation as long as you do it to both sides


3x-3=x-4
get placeholder to one side
minus x from both sides
3x-x-3=x-x-4
2x-3=0-4
2x-3=-4
add 3 to both sides
2x+3-3=3-4
2x+0=-1
2x=-1
divide both sides by 2
x=-1/2

3x-3=x-4

Add 4 to both sides

3x+1=x

Subtract 3x from both sides

1=-2x

Divide both sides by -2

x=-1/2

Slav-nsk [51]

1) Answer: -\frac{3}{2}

<u>Step-by-step explanation:</u>

f(x) = 6x⁻¹

f'(x) = -6x⁻²

     = \frac{-6}{x^{2}}

f'(-2) = \frac{-6}{(-2)^{2}}

        = -\frac{6}{4}

        = -\frac{3}{2}

*****************************************************

2) Answer: \frac{1}{4}

<u>Step-by-step explanation:</u>

f(x) = -9x⁻¹

f'(x) = 9x⁻²

     = \frac{9}{x^{2}}

f'(6) = \frac{9}{(6)^{2}}

        = \frac{9}{36}

        = \frac{1}{4}

What is 4x+2(3x7)= if x=5
Sedbober [7]

4x + 2(3\cdot7) = ?

Now we must solve this equation if x = 5. To do so we must substitute:

4(5)+2(3\cdot7)\\

Using PEMDAS we will solve for the parenthesis first.

4(5)+2(21)

Multiply:

20+(42)

Add:

20+42=62

Final answer: 62
