Answer:
x = 3
Step-by-step explanation:
<u>Step 1: Subtract 5 from both sides</u>
3x + 5 - 5 = 14 - 5
<em>3x = 9</em>
<u>Step 2: Divide both sides by 3</u>
3x / 3 = 9 / 3
<em>x = 3</em>
Answer: x = 3

Y=-5/9X+7
Step-by-step explanation:
Answer:
x=1/3, x=-2/3
Step-by-step explanation:
9x^2 +6x -3x -2=0
6x and -3x add up to 3x. You need four terms to factor.
Then you factor=
3x(3x+2)-1(3x+2)=0
(3x-1)(3x+2)=0
Then you can make two equations
3x-1=0 and 3x+2=0 because to multiply to get 0, at least one will be 0.
3x-1=0
3x=1
x=1/3
3x+2=0
3x=-2
x=-2/3
So your answers are x=1/3, x=-2/3

Answer:
3
Step-by-step explanation:
3^10= 3^7(x^3)
59049= 2187(x^3)
59049/2187= x^3
27=x^3
Do the square root of 3 to both sides and you end up with x=3.
Hope this helped :)
