Step 1. Multiply first equation with -3 and the second one with 2. You'll get:

Step 2. Add both equations together. You'll get:

, which gives x = -2
Step 3. Replace x = -2 in the first equation and calculate y.

The solution is: x=-2, y=5
 
        
        
        
Answer:
y = 3x - 7
Step-by-step explanation:
The <em>point-slope formula</em> for a straight line is
y – y₁ = m(x – x₁)
x₁ = 4; y₁ = 5; m = 3     Substitute the values
y – 5 = 3(x - 4)             Remove parentheses
y – 5 = 3x - 12             Add 5 to each side
      y = 3x - 7
The graph is a straight line with a y-intercept at y = -7 and a slope = 12/4 = 3.
 
        
             
        
        
        
<span>3x+4=y+5, then y+5=3x+4
It is called: reflexive property

<span>x = y and y = 10, then x = 10
It is called: equality substitution property
