The length of the two pieces is given: 10 and x-2.

The two pieces' lengths tally up to 2x-3.

So, if we put the pieces together, we must obtain the total:

$10+x-2 = 2x-3$

$x+8=2x-3$

$x=11$

So, GF is x-2, i.e. 11-2=9

The answer is 4. Since 12+ 12 = 24, I added 4 + 4, which made 42.
So the length of the width of the rectangle is 4.
Hope this helps!

Solve the system by substitution: <br> 3x + 2y = 26<br> Y=x + 3

Orlov [11]

Answer:

x = 4

Step-by-step explanation:

3x + 2y = 26

y = x + 3

Plug in the equation for y

3x + 2(x + 3) = 26

Multiply the 2 with what is in the parantheses

3x + 2x + 6 = 26

Combine like terms and solve for x

5x + 6 = 26

5x = 20

x = 4
