Combine like terms
18x-18=180
Add 18 to both side
18x=198
Divide 18 on both side
x=11

Answer:
4:8
Step-by-step explanation:
The 1 from the 1:2 is being multiplied by 4 for the 4:_, so the 2 from the 1:2 must also be multiplied by 4. 4 x 2 = 8
Perimeter is the addition of all the sides
x-2+x+3x+1=2x-5+x+4+6x-7; since their perimeters are equal
5x-1=9x-8
collect the like terms
-1+8=9x-5x
7=4x
x=7/4
x=1.75
