Let's say Ronnie is thinking of X.
If 2(x) = x+5, we would first distribute the 2.
2x = x+5
We would then need to isolate the variable. We would do so by getting all variables to one side. The easier choice would be to subtract x from both sides.
2x=x+5
-1x -1x
This becomes
x=5
Ronnie is thinking of the number five.
5•2=10 and 5+5=10.

Answer:
$54.25
Step-by-step explanation:
4/5 yards of lace = $5.60
Price per yard = 5.60 ÷ 4/5
= 5.60 × 5/4
= 28 /4
= $7 per yard
The class decided to buy another 7 3/4 yd
Cost of 7 3/4 yd = cost per yard × number of yards
= $7 × 7 3/4
= $7 × 31/4
= 217 / 4
= $54.26
Cost of 7 3/4 yd = $54.25
