<span>The sum of two numbers is 50. The smaller number is 18 less than the larger number. What are the numbers?
-----
Equations:
x + y = 50
x = y - 18
-------------------
Add and solve for "x"::
2x = 32
x = 16
-----
Solve for "y"::
16 + y = 50
y = 34
-----------------
Hope I helped!

4 2/3+5x=7-2x
Add 2x to both sides.
4 2/3+7x=7
Subtract 4 2/3 on both sides.
7x=2 1/3
7x=7/3
Divide by 7 on both sides.
x=1/3
answer: x=1/3
Answer:
7) 230mm
8) 98m
Step-by-step explanation:
7)
7x+8+6x+6+9x-4 =22x+10
if x is 10 mm, 22(10)+10 =230mm
8) perimeter of rec =2( l + w )
=2 ( 2x-5+2x+6 ) = 8x + 2
if x is 12 metres, 8(12)+2 =98m
The actual distance between the cities is 50 miles
