Answer:

$3\neq -3$

False

Step-by-step explanation:

$y=3x-9\\\\x-\frac{1}{3}y=-3$

You substitute $y$ for the second equation.

$x-\frac{1}{3} y=-3\\\\x-\frac{1}{3}(3x-9)=-3$

Then you have to distribute $-\frac{1}{3}$ .

$x-x+3=-3$

Combine like terms.

$3\neq -3$

9966 [12]

Answer:

Without tax the shoes would cost £55.9.

Step-by-step explanation:

To get this you take the £86 and multiply it by 0.65 because with the 35% sale you are paying for 65% of the item. You get this number by subtracting 35 from 100 and convert it into a decimal.
