Solve the system by substitution. 2x - y = -3, 2x-2y = -2
Sonja [21]

Answer:// Solve equation [1] for the variable  y

 [1]    y = 2x - 3

// Plug this in for variable  y  in equation [2]

  [2]    -2•(2x-3) + 2x = 2

  [2]     - 2x = -4

// Solve equation [2] for the variable  x

  [2]    2x = 4

  [2]    x = 2

// By now we know this much :// Solve equation [1] for the variable  y

 [1]    y = 2x - 3

// Plug this in for variable  y  in equation [2]

  [2]    -2•(2x-3) + 2x = 2

  [2]     - 2x = -4

// Solve equation [2] for the variable  x

  [2]    2x = 4

  [2]    x = 2

// By now we know this much :

   y = 2x-3

   x = 2

// Use the  x  value to solve for  y

   y = 2(2)-3 = 1

   y = 2x-3

   x = 2

// Use the  x  value to solve for  y

   y = 2(2)-3 = 1

Solve |2x + 1| = 10<br> {9/2, 11/2}<br> {-9/2, 9/2}<br> {-11/2, 9/2}
prisoha [69]
The answer is -11/2, 9/2

Explanation

You have to rewrite the absolute value equation as two separate equations.
2x+1=10
2x+1=-10

Then you solve for X in each equation.
2x+1=10 would give you 9/2

2x+1=-10 would give you -11/2

So your final solutions would be x1= -11/2 x2= 9/2
