First let’s try to cancel out the x
5x + -5x = 0
Add the y and the numbers together
-3y + -2y = -5y
26 + -16 = 10
-5y = 10
y = -2
Use y=-2 in one of the equations
-3(-2) + 5x = 26
6 + 5x = 26
5x = 20
X = 4
So
Y= -2
X= 4

hope it helps :P
perimeter means add the side
(x+4) +( x+8)+(2x-3) =P
x+x+2x+4+8-3=P
4x-9 =P
Answer:
372.5
Step-by-step explanation:
Order the numbers least to greatest:
110, 345, 400, 640
Add the two middle numbers:
