The only way to do that is with +7 and -7 .
Answer:

Step-by-step explanation:
-5(2x - 5) = 8 + (5 - 2x)
-10x + 25 = 8 + 3x
-10x - 3x = 8 - 25
-13x = -17

3 * 171 and you are going to get 513
Answer:
L=6 cm l=3
Step-by-step explanation:
x+y=45
L=2l
Big Square Area
L*L=x
Little Square
l*l=y
Substituting
(L*L)+(l*l)=45
(2l*2l)+(l*l)=45
(4l^2)+(l^2)=45
5l^2=45
l^2=45/5
l^2=9
l=sqrt(9)
l=3
L=2(3)
L=6
