so you need to get "a" alone
a-2+3=-2
subtract 3 from both sides
a - 2 = -2-3
a - 2 = -5
then add two to both sides
a = -3
as your answer
its 76 i think
i told my teacher and she it was true
So with the given information, I make the length equal x and the width equals x+61. Remember a rectangle has two pairs of equal sides.
So then the equation is 4x+122=406
Do systems and you will find that x equals 71.
The length is 71cm
The width is 71+61=132cm
Answer:
x=20, 3x=60, 2x=40
Step-by-step explanation:
3x+80+2x=180, so
x=20
