Answer:
Step-by-step explanation:
x = 20
Divide the lengths to find the scale :
35/7 = 5
Now divide the width by the scale to get the scaled width:
30/5 = 6 inches
the scaled drawing is 7 x 6
area of scaled drawing = 7 x 6 = 42 square inches
First, you need to get rid of the fraction by multiplying both sides by 20 and you would get:
4(x + 2) = 5(x + 6)
Now, you need to get rid of the parenthesis by distributing:
4x + 8 = 5x + 30
Subtract both sides by 5x:
-x + 8 = 30
Subtract both sides by 8:
-x = 22
Now, divide both sides by -1:
x = -22
P.S.: You don't really need a calculator to solve.
