Explanation

Given x = 2, let's find y:

2x + y = 10

2(2) + y = 10

4 + y = 10

y = 6

Now, xy = 2 × 6 = 12

The equation represents the total cost Bahadur pays, which includes the original price (x) plus the 4% tax (0.04x).

So, total cost = x + 0.04x = 1.04x

(3y + 5) + (2y - 4)

= 3y + 5 + 2y - 4

= 5y + 1

Explanation

y/(y+3) = 2/3

3y = 2(y+3)

3y = 2y + 6

y = 6

Explanation

x + 2y = 8

y = 3

x + 2(3) = 8

x + 6 = 8

x = 2

xy = 2 × 3 = 6

x(a - c) + y(c - a)

= x(a - c) - y(a - c)

= (a - c)(x - y)

Explanation

The degree of a polynomial is the highest sum of exponents in a term:

2x⁴: degree 4

x³y: degree 4

xy³: degree 4

Highest degree is 4, so it's Biquadratic.

Explanation

Let the numbers be x, x+2, x+4

x + (x+2) + (x+4) = 39

3x + 6 = 39

3x = 33

x = 11

Explanation

"Eight times y" means 8y

"plus 3" means + 3

"gives 85" means = 85

Putting it together: 8y + 3 = 85
