Lan needs to solve 23 = y + 40. What is the step that shows the inverse operation needed to solve this equation. Find the value of y. Y=

y=17

Step-by-step explanation:

We move all terms to the left:

23-(y+40.)=0

We add all the numbers together, and all the variables

-(y+40)+23=0

We get rid of parentheses

-y-40+23=0

We add all the numbers together, and all the variables

-1y-17=0

We move all terms containing y to the left, all other terms to the right

-y=17

y=17/-1

y=-17

rectangle that is ther answer you

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
