Answer:

  • 3(x + 1) - 2x - 7 = x - 4

Step-by-step explanation:

The equation has infinitely many solutions if LHS and RHS are same regardless the value of the variable.

Let's simplify the LHS and make sure it is same as RHS.

Let the missing numbers are a and b.

  • a(x + 1) - 2x - b = x - 4
  • ax - 2x + a - b = x - 4
  • (a - 2)x + (a - b) = x - 4

Find a and b:

  • a - 2 = 1 ⇒ a = 3
  • a - b = - 4 ⇒ 3 - b = - 4 ⇒ b = 7
