12=4.7k+11.5 how do you do this step by step? answer for k

k=0.106383

Step-by-step explanation:

Let's solve your equation step-by-step.

12=4.7k+11.5

Step 1: Flip the equation.

4.7k+11.5=12

Step 2: Subtract 11.5 from both sides.

4.7k+11.5−11.5=12−11.5

4.7k=0.5

Step 3: Divide both sides by 4.7.

4.7k

4.7

=

0.5

4.7

k=0.106383

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
