Berta worked to solve a system of equations. 4x y = –5 x – y = –5 Step 1: ??? Step 2: x = –2 Step 3: 4(–2) y = –5 Step 4: –8 y = –5 Step 5: y = 3 Berta determined that the solution is (–2, 3). Which could have been the equation Berta found in step 1? 4x = 0 5x = 10 5x = –10 5x = –25.

Respuesta :

Berta worked to solve a system of equations,Berta determined that the solution is (–2, 3) ,The equation Berta found in step (1)5x = -10

Given: Solved equations in steps:-

  • Step(1):   we need to find
  • Step(2):  x=-2
  • Step(3):  4(-2)Y=-5
  • Step(4):  -8y=-5
  • Step(5):   y=3

Now, given Four steps of an Equations and according to that equations we have to find the first step which is missing.

We will sove the equation and find step(1)

                                  [tex]\rm 4x + y = -5\\ x - y = -5 \\5x = -10\\x = -2[/tex]

Therefore, The equation Berta found in step (1)5x = -10
