Solve for x
4= tx

gh= 7x

2d + x = w

Step-by-step explanation:

(a)  We are to solve 4 = tx for x.  Isolate x by dividing both sides by t:

tx      4

=

 t       t

This yields the formula x = 4/t

(b) If gh = 7x and we want a formula for x, we divide both sides by  7 to isolate x:

gh       7x

=   or  x = gh/7

  7        7

(c) To solve 2d + x = w for x, subtract 2d from both sides.  We get:

x = w - 2d

$450.00 for 6 weeks

or

$300

step-by-step explanation:

$200.00 for first week $50.00 x5 equals $250 plus $200 equals $450.00 for six weeks.

$200 for first week

$200 x 0.10 = $20

$20 x 5 = $100

$200 + $100 = $300
