21 and 21
(it's a square)
and yes, a square is a rectangle
X = 3
y = -1
get the x or y by itself first (second eq. is easier)
So, x + 2y = 1
-2y -2y
Now we get:
x = -2y +1 Plug it into the other equation.
2x + 3y = 3
2(-2y +1) + 3y = 3
-4y + 2 + 3y = 3
-1y +2 = 3
+1y -3 -3 +1 y
y = -1 (plug into either eq to get x)
<span>x + 2y = 1
</span>x+2(-1) = 1
x-2=1
+2 +2
x = 3
starts with 20 smthing x3 +4 = 20 but what is it ???? hmmmm if you think more you can fiqure it out by just finding random numbers so use ur brain i guess???
Answer:
X=2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
120(2x−2)=240
(120)(2x)+(120)(−2)=240(Distribute)
240x+−240=240
240x−240=240
Step 2: Add 240 to both sides.
240x−240+240=240+240
240x=480
Step 3: Divide both sides by 240.
240x
/240
=
480
/240
x=2
