What value of x makes the following equation true?<br> 15+3x=3(2−2x)
Alinara [238K]

Answer:

\boxed {x = -1}

Step-by-step explanation:

Solve for the value of x:

15 + 3x = 3(2 - 2x)

-Use <u>Distributive Property</u>:

15 + 3x = 3(2 - 2x)

15 + 3x = 6 - 6x

-Take 6x and add it to 3x:

15 + 3x + 6x = 6 + 6x - 6x

15 + 9x = 6

-Subtract both sides by 15:

15 - 15 + 9x = 6 - 15

9x = -9

-Divide both sides by 9:

\frac{9x}{9} = \frac{-9}{9}

\boxed {x = -1}

Therefore, the value of x is -1.

Please I need like an explanation of how it was done.
a_sh-v [17]

Answer:

  the point is (3, 3) . . . . . . y = 3

Step-by-step explanation:

Write the point-slope equation of the line through the point you know. Then evaluate that equation for x=3 to see what the value of y is.

Point-slope form:

  y = m(x -h) +k . . . . slope m through point (h, k)

  y = -1/2(x -9) +0 . . . . line with slope -1/2 through point (9, 0)

For x=3, the value of y is ...

  y = -1/2(3 -9) + 0 = -1/2(-6) = 3

The value of y is 3.

A farmer planted 3 types of trees on 22 acres of land. He planted 48 trees per acre. What is the total of trees the farmer plant
antoniya [11.8K]
Hey there! :D

He planted 48 trees per acre. Ignore the '3 types of trees' part. I think the question is trying to confuse you. Multiply 48 by 22.

48*22= 1056

The farmer has planted 1056 trees.

I hope this helps!
