Mr. Pham wrote the equation below on the board. 18 minus 7 x = negative 20.5 What is the value of x?

x = 5.5

Step-by-step explanation:

Step 1: Write out the equation

18 - 7x = -20.5

Step 2: Subtract 18 on both sides

-7x = -38.5

Step 3: Divide both sides by -7

x = 5.5

And we have our final answer!

its 8

step-by-step explanation:

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
