The equations would be:
x=18+3y
x+y=54
(substitute x in the second equation with 18+3y)
18+3y+y=54
(combine like terms and solve for y)
y=9
(plug y into the second equation to find x)
x+9=54
x=45
The answer is 100 when I need the math I found 100
Unless if you have the solution for a you can find b
Answer:
the answer is 50cm
Step-by-step explanation:
