Use the properties of equality to solve the equation 3x +2 - x = 11x + 9

-7/9

Step-by-step explanation:

To solve this equation you must isolate the variable.

First, add like terms (terms with the same variable and degree)

2x+2=11x+9

Then, subtract 2x from both sides

2=9x+9

Next, subtract 9 from both sides

-7=9x

Finally, divide both sides by 9

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
