In linear equation ,316 is the number of seats for each aircraft .

What are instances of linear equations?

  • A linear equation with one variable is one that contains just one variable.
  • It has the formula Ax + B = 0, with A and B being any two real numbers and x being an ambiguous variable with only one possible value. One such linear equation in one variable is 9x + 78 = 18.

Aircraft B: x seats

Aircraft A: x+ 127 (127 more than B)

Total seats on both is 505.

So, x+127+x = 505

Combine like terms

2x+127 = 505

Subtract by 127 both sides

2x = 505-127 = 378

Divide by 2 on both sides

x = 189 seats (B)

x + 127 =189 + 127 =   316 (A)
