Answer:
2(2y - 1) - y = 7
Step-by-step explanation:
I guess the 2 equations are
2x - y = 7
x = 2y - 1
substitution message that you use one equation to express one variable by the other, and then you use that in the other equation to get one equation for one variable. then you solve for that, and use that result in the first equation to since for the second variable.
the equations are already defined that way, that the second equation directly defines x as an excision of y.
so, this needs to be used then in the first equation.
and that makes
2(2y - 1) - y = 7
the correct first step.

Im not 100% sure tho
        
                    
             
        
        
        
Answer:

Step-by-step explanation:
The formula for distance is: 

Where (x₁, y) and (x₂, y₂) are the points. 
We are given (-6, 6) and (-3, 3). If we match the value and its corresponding variable, we see that: 
- x₁= -6 
- y₁ = 6 
- x₂ = -3 
- y₂ = 3 
Substitute the values into the formula.

Solve inside the parentheses. 
- -3 --6 = -3+6 = 3
- 3-6 = -3

Solve the exponents. 
- (3)²= 3*3= 9 
- (-3)²= -3*-3 =9

Add. 


Round to the nearest tenth. The 4 in the hundredth place tells us to leave the 2 in the tenth place. 

The distance between the two points is apprximately <u>4.2</u>
