Answer: x = -2
Step-by-step explanation: When we have this kind of a setup, we want to put our variables together on one side of the equation and our numbers together on the other side of the equation.
So first, let's put our variables together on the left side
by subtracting 6x from both sides of the equation.
That gives us 2x + 5 = 1.
Now we can move our numbers to the right by subtracting
5 from both sides and we get 2x = -4.
Since <em>x</em> is being multiplied by 2, divide both sides
by 2 to get <em>x</em> by itself and we end up with <em>x = -2</em>.
Answer:
x = 3, x = 6
Step-by-step explanation:
Using the rules of logarithms
log x - log y = log (
)
log
⇔ nlog x
x = n ⇔ x = 
Given
2
x - (x - 2) - 2 = 0 ( add 2 to both sides )
x² - (x - 2) = 2
(
) = 2
= 3² = 9 ( multiply both sides by x - 2 )
x² = 9(x - 2) ← distribute
x² = 9x - 18 ( subtract 9x - 18 from both sides )
x² - 9x + 18 = 0 ← in standard form
(x - 3)(x - 6) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 3 = 0 ⇒ x = 3
x - 6 = 0 ⇒ x = 6
Answer:
90
Step-by-step explanation:
120 - (120/4)
120 - 30 = 90
Answer:
14!
Step-by-step explanation:
Yes 14 itself, 70/14=5, and 14/14=1, can’t get bigger than that! :D
i hope this helps ;)
