Answer:
x=7
Step-by-step explanation:
You should look to units of measure when setting up problems. when math is done correctly, the units cancel out just as numbers and variables do.
(miles / hr) * hr = miles
Speed = (miles / hr)
So if the Train W is traveling at x miles/hr
Then Train E is traveling (x+14) miles/hr
The combined distance they two trains travel is 320 miles
2x + 2(x+14) = 320
2x + 2x + 28 = 320
4x + 28 = 320
4x = 292
x = 292/4
x = 73 miles/hr
remember we set x as the speed for Train W
so Train E is going 73 + 14 = 87 miles/hr
Hello,
An old way i used to do it was by doing

or you could just put it in a caculator
hope this helps
plz mark me as brainliest
Step 1: Subtract 8 from both sides.
5/4y+ 8− 8= 17.5− 8
5/4y = 9.5
Step 2: Multiply both sides by 4/5.
(4/5) * (5/4y) = (4/5) * (9.5)
y = 38/5
