(-2x + - 11)
what’s the no need for explanation l

−3x+15

Step-by-step explanation:

Distribute the Negative Sign:

=−2x+4+−1(x−11)

=−2x+4+−1x+(−1)(−11)

=−2x+4+−x+11

Combine Like Terms:

=−2x+4+−x+11

=(−2x+−x)+(4+11)

=−3x+15

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
