1 cm = 10 mm
? cm = 987 mm
987/10 = ? cm = 98.7 cm.
There are 98.7 cm in 987 mm.
Hey there!
First, we will do the subtraction with the two like terms on the left. I know they're like terms because although they have different coefficients, they have the same variable.
We have:
2n=4
Divide both sides by 3 to get:
n = 2
Hope this helps!
