7(w+2)=-6(2w-1)+3w<br>solve for w.​
Goshia [24]

9514 1404 393

Answer:

  w = -1/2

Step-by-step explanation:

Eliminate parentheses, collect terms:

  7w +14 = -12w +6 +3w . . . eliminate parentheses

  7w +14 = -9w +6 . . . . . . . . collect terms

  16w +14 = 6 . . . . . . . . . . . . add 9w

  16w = -8 . . . . . . . . . . . . . . . subtract 14

  w = -1/2 . . . . . . . divide by 16, reduce the fraction

__

<em>Check</em>

  7(-1/2 +2) = -6(2(-1/2) -1) +3(-1/2)

  7(3/2) = -6(-2) -3/2

  21/2 = 12 -3/2 . . . . . true, answer checks OK

In which question is r = -17 a solution?
devlian [24]

Answer:

None

Step-by-step explanation:

Simply solve each linear equation and get value of R.

Or another way can be to put value of R in all four options and find whether left hand side is equal to right hand side or not.

A) 3-\frac{2R}{4}=10

   -\frac{R}{2}=7

   R = -14

B)  \frac{3}{4}-2R =10

     -2R=10-\frac{3}{4}

    R = -37/8

C)  3(R-4)=10

     R-4=\frac{10}{3}

    R=4+\frac{10}{3}

  R = 22/3

D) 3-\frac{R}{4}=10

    R = -28

So, none of the option's are having solution R =-17.
