Kendra has $32 and is planning to save $25 each week. She is saving to buy a new phone that costs $257.00. Write an equation to find w, the number of weeks until she will have enough money for the phone.

257.00=25w+32

Step-by-step explanation:

W is the number of weeks. It will take 9 weeks for her to save up to the new phone.

1) the property is   ixi = a ⇔x = a   o x = -a

4(x-5)+3= 15⇒4x-20+3 = 15⇒4x-17= 15⇒4x = 15+17⇒4x = 32⇒x =32/4= 8

4(x-5) +3= -15⇒4x-20 +3 = -15⇒4x-17= -15⇒4x =-15+17⇒4x = 2⇒x =2/4= 1/2

the values are x =8 and x = 0,5
