10 = z + 6 (show work)

4

Step-by-step explanation:

10=z+6

or, z+6=10

or, z=10-6

or,z=4

May this help you

Step-by-step explanation:

10 = z + 6

Now, subtract both sides with 6

10-6=z+6-6

4=z

Hence, the value of z is 4

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
