Area=legnth times width
36 and 1/4=8 and 3/4 times width
conver to imrpoer
36 and 1/4=145/4
8 and 3/4=35/4
145/4=35/4 times x
times both sides by 4
145=35 times x
divide both sides by 35
29/7=x
4 and 1/7=x
answer is 4 and 1/7=legnth
Subtract 4x from both sides
4x +2 = 7x - 13 would then simplify to
3x - 13 = 2 ( you can switch the problem around as long as you dont switch the variables around )
then you have to + 13 which simplifies to
3x = 15
then you divide by 3 which equals
x=5
Answer:
x = 14
Step-by-step explanation:
5(22-x)=40
5(22-14)=40
5(22)=110 5(-14)=-70
110-70=40
