You want l on the left of the equation so I would first rewrite it
You don't want the 2w term on the left of the equality so add 2w to each side. This maintains the equality and gives
You are almost there, you have 2l on the left rather than l so divide both sides by 2 to get
Now for practice find l if p = 3l  2w and let me know what you got for l. Penny
Hi there. With any equation like this, you just have to make sure that what you p = 2l + 2w first remove the added term 2w by subtracting 2w from both sides: p  2w = 2l + 2w  2w now remove the 2 from the 2l by dividing both sides by 2: ( p  2w ) / 2 = 2l / 2 So l is p / 2  w. That's how you solve one of these equations for Hope this helps,
