If you're solving the equation 4x = 75 + x simply subtract "x" from both sides of the equation leaving you with the equivalent equation, 3x = 75 Now here we can see by inspection that 3(25) = 75... therefore x = 25
Answer:
y = 60
Step-by-step explanation:
<h3>Step 1: Make sense of the given</h3>
"The ratio of y to x is 3"
This means that,
"The sum of y and x is 80"
This means,
<h3>Step 2: Make use of the facts</h3>
If , then .
We can plug this into the other equation by substitution:
This simplifies to:
Which we can solve out and get:
.
<h3>Step 3: Plug and Chug</h3>
We solved for x, but we need the value of y.
So, we go back to the equation we first derived: "".
And now we substitute the value of x, into this.
By solving this out, we get:
So, the value of y is 60.
First one is 1 x 10^6
second is 2 x 10^8
third one is 157 times
