What is ─7 ─ 4b = ─5b sovled for the variable

b = 7

Step-by-step explanation:

Add 4b to both sides

You then get -b = -7

You want to multiply both sides by -1 because you can't have a negative variable

what are you trying to solve here

step-by-step explanation:

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
