As per linear equation, the expression by which the total yards gained by Jordan's football team is measured is (x₁ - x₂).
What is a linear equation?
A linear equation is an equation where the variable of the equation has the highest power of degree one.
Let, x₁ = The gain of Jordan's football team on their first play = 12 yards
x₂ = The loss of Jordan's football team on their second play = 8 yards
Therefore, The total yards gained by Jordan's football team = (x₁ - x₂)
= (12 - 8) yards = 4 yards.
Therefore, the expression by which the total yards gained by Jordan's football team is measured is = (x₁ - x₂).
