Question

4x+6y=80

find xy please and tell the solution also I am in sixth standard and I want to learn about linear equations in two variables​

Answer 1

Answer:

please mark me thanks please

Step-by-step explanation:

4x + 6y = 80

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-6y' to each side of the equation.

4x + 6y + -6y = 80 + -6y

Combine like terms: 6y + -6y = 0

4x + 0 = 80 + -6y

4x = 80 + -6y

Divide each side by '4'.

x = 20 + -1.5y

Simplifying

x = 20 + -1.5y

Answer 2

Answer:

$4x + 6y = 80 \\ 4x = 80 - 6y \\ x = 80 - 6y \div 4 \\ x = 20 - 6y \\ put \: value \: of \: x \: in \: equation \\ 4 \times (20 - 6y) + 6y = 80 \\ 80 - 24y + 6y = 80 \\ 80 - 80 = 24y - 6y \\ 0 = 18y \\ 0 \times 18 = y \\ y = 0 \\ put \: vlue \: of \: y \: in \: euation \\ 4 \times x + 6 \times 0 = 80 \\ 4x + 0 = 80 \\ x = 80 \div 4 \\ x = 20$

Step-by-step explanation:

y=0

x= 20
