Answer:
Step-by-step explanation:
You have to multiply the smaller one by a common number to make them equal. If you multiply it by 4;
4x4=16
2x4=8
2.5x4=10
So, plugin to get, x-3=10.
x=13.
Answer: y= -2x - 4
Step-by-step explanation:
This is a straight line, so it can be expressed by y = mx + c.
Here c is y-intercept, which means where line cuts the y-axis. We can see from the graph that the line cuts the y-axis at -4.
So, c = -4.
m is slope.
Use slope formula to find m.
m = ( -4 - 0 ) / ( 0 -(-2))
m = -4 / 2
m = -2
Now put values into this equation
y = mx + c
y = -2x - 4
Option C: The solution is 
Explanation:
The given expression is 
We need to solution of the given expression.
The solution of the given expression can be determined by adding the two expressions.
Let us remove the parenthesis.
Thus, we have,
