Mr. DeBerry plans to extend the school yard 3 1/2 times the current length of 4 2/3 in the next 2 months. How long will the school yard be at the end of 2 months

im pretty sure it would be 5 am, hope that , and give brainliest and guys if this is right then press the button and give 5 stars

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
