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!

r-ruslan [8.4K]

Answer:

Add -4x to both sides--> 6x+9=4x-3 and 2x+9=-3

multiply both sides by -1/4 --> -4(5x+7)=-18 and 5x-7=4.5

multiply both sides by 1/4--> 12x+4=20x+24 and 3x+1=5x+6

multiply both sides by -4--> -5x/4=4 and 5x=-16

add -4 to both sides--> 8-10x=7+5x and 4-10x=3+5x
