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

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
