Answer:

x=9/2

Step-by-step explanation:

Area must be same, so

10x=(3+x)6

10x=18+6x

10x-6x=18

x=18/4

x=9/2

Answer:

x = 9/2

Step-by-step explanation:

Let the left-most figure be Figure A.

Let the right-most figure be Figure B.

Figure A area:

10 cm * x cm = 10x cm squared

Figure B area:

(3 cm + x cm) * 6 cm = 18 cm + 6x cm

Create the equation:

10x = 18 + 6x

Solve:  

10x = 18 + 6x  

4x = 18

x = 18/4

x = 9/2
