11 3/8 would be the simplified version and 91/8 would be the other way.
It's already in scientific notation form;
Answer of your question,
3x+46 = 10x-80
7x = 34
x = 4.85
I'm guessing this is a slope problem, so the equation would be like this: y = mx + b where m is the slope and b is the y-intercept.

Using this,

Which is equal to,
Answer:
16
Step-by-step explanation
6 = x/4 + 2
subtract 2 from both sides
4 = x/ 4
since its dividing x and 4 you need to multiply 4 on both sides
16 = x
