The first thing you want to do is combine like terms. This means you should have all the x's on one side and the constants (numbers) on the other side. You can subtract 5x from both sides of the equation and then add 7 to both sides. This gives you -2x=26. Divide both sides be -2 to isolate the variable and your answer is x=-13. Hope this helped!

3x -7 = 5x + 19
subtract 19 to both sides 
3x -2 = 5x
subtrct 3x from both sides
-2=2x
divide two by both sides
-1 = x

Solve the system using substitution:<br> y = -6x + 7<br><br> 3x – 2y = 16<br><br> helppp
bearhunter [10]

Answer:

x=-6 y=-1

Step-by-step explanation:

// Solve equation [2] for the variable  y  

 

 [2]    y = -x - 7

// Plug this in for variable  y  in equation [1]

  [1]    3x - 2•(-x -7) = -16

  [1]    5x = -30

// Solve equation [1] for the variable  x  

  [1]    5x = - 30  

  [1]    x = - 6  

// By now we know this much :

   x = -6

   y = -x-7

// Use the  x  value to solve for  y  

   y = -(-6)-7 = -1  

Solution :

{x,y} = {-6,-1}

Determine the slope between (4, 2) and (-3, 5) ~hurry please~
SpyIntel [72]

Answer:

A.-3/7

Step-by-step explanation:

the slope formula is

m = (y2 - y1) / (x2-x1)

The point (4, 2) is (x1, y1) and the point (-3, 5) is (x2, y2). Now you have to substitute in the slope formula:

m = (5 - 2) / (-3 - 4)

m = 3 / -7

m = -3/7
