Please Solve Its Much Easier Than I Think Probably Im Pretty Sure Im Over Thinking class=

Sagot :

x=16cm

y=17cm

Step-by-step explanation:

area of the sheet = 4y

area of the hole = 3x

4y-3x=20

y=x+1, so let's substitute and solve for x

4(x+1)-3x=20

4x+4-3x=20

x+4=20

x=20-4

x=16

y=17

note: my keyboard is starting to act weird and I left out the units (cm) in the explanation to simplify things
