Step by step solution :Step 1 :Equation at the end of step 1 : y - (((22•3x2) - 9x) + 4) = 0 Step 2 :Equation at the end of step 2 : y - 12x2 + 9x - 4 = 0 Step 3 :Solving a Single Variable Equation :

3.1 Solve y-12x2+9x-4 = 0

In this type of equations, having more than one variable (unknown), you have to specify for which variable you want the equation solved.

James has just sold his motorbike for £1,890. He bought the motorbike for £2,700. What was his percentage loss? %

Usimov [2.4K]

£2.700 - £1890 = £810

£ (money) -------------- percentage (%)
2.700 -------------------- 100
810 ----------------------- x

2700*x = 810*100
2700x = 81000
$x = \frac{81000}{2700}$
$\boxed{x = 30}$

Answer:
Percentage loss = 30%
