Solve for x:16^(4x-3)=8^(2x+4)

x=4.75

Step-by-step explanation:

16(4x-3)=8(2x+4)

16*4x-3=8*2x+4

    -2x       -2x

16*2x-3=8*4

multiply 8*4=32

16*4x-3=32

-16         -16

4x-3=16

   +3 +3

4x=19

divide 4 by both sides

x=4.75

step-by-step explanation:

so first find out how much each is worth.

quarter= 25 cents

dime= 10 cents

pennies= 1 cent

then multiply each by how much each is worth.

200                     150                   300

x                         x                     x   1

  25                       10              

                                  300

1000                     1500

+                          

4000                                      

5000                                  

then count 2 from the back and add a period.

$50.00

$15.00

$3.00

and then add them

  $50.00

+

  $15.00

+

    $3.00

$68.00

so sunghee has $68.00

use substitution to solve each system of equations. y = x + 5 3x + y = 25 62/87,21 y = x + 5 3x + y = 25 substitute x + 5 for y in the second equation. substitute the solution for x into either equation to find y. the solution is (5, 10)
