8x-11+5x+2x+6=180 what is the measurement for x.
Verizon [17]

I assume you're looking for the value of x?

Combine like terms: 8x+5x+2x-11+6=180 -> 15x-5=180

Add 5 to both sides: 15x=185

Divide both sides by 15: x=12 1/3

So x is 12 1/3 or 37/3

Hope this helped!

How can I write an equivalent expression for 4+3(5+ x)
Firlakuza [10]
To write an equivalent expression for the following all that you would need to do is to add the values of 4 and 3 together

As these numbers come before the expression, and then distribute the final answer into the brackets.

Here it would be 35 + 7x.

This is the final answer.

Both of these are equal to each other one being simplified and the other being complex.
