Question

Can you help me this tteacher answer the box and also the questions

Answer 1

Explanation:

2) x - y = 2/3

`x = (2)/(3) + y`

3) 3x +2y = 6

3x = 6 - 2y

Divide the equation by 3

`(3x)/(3)=(6)/(3)-(2y)/(3)\\\\x = 2 - (2)/(3)y`

4)

`(1)/(4)x + y = 2\\\\ y = 2 - (1)/(4)x`

5) 4x - 3y = -33

-3y = -33 - 4x

Divide the equation by (-3)

`(-3)/(-3)y=(-33)/(-3) - (4)/(-3)x\\\\ y = 11 + (4)/(3)x`

1) Yes, it was easy to solve one variable in terms of the other.

2) Yes, it was easy to solve for y in terms of x. Coefficient of x was a fraction.

3) It will be easy if we take the value of x as multiples of 3

Example: if x = 3,

`y = 11 + (4)/(3)*3 \\\\y = 11 + 4\\\\y = 15`

It is easy to plot (3 ,15)
