u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w

maya’s expression will generate the wrong sum because she violated the commutative property.

step-by-step explanation:

it would have to be 3/0

well, if it's triangular garden, the triangle could represent the garden.
