Question

The side of rectangle are 4x-y, 4x+3, 3x+1, x+6y

Answer 1

Step-by-step explanation:

Yes that's right. You have to equate the expressions for widths and for the lengths, since left and right widths (and lengths) have the same dimensions.

You may rewrite the equation for y=3x+3÷6 as

y = (3x + 3)/6

And now you have an expression for y, we can substitute it to the other equation you got:

x = y + 1

x = (3x + 3)/6 + 1
