Let T be relation on R defined as follows
T= {(x, y)∈RxR| exist n∈Z (y=x·10^n)}
is T equivalence relation?

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

answer: y = -2.5x - 15
