What is W in this equation, - 12u+13=8w-3

w = (-3/2) u + 2

Step-by-step explanation:

Since we don't know the value of u, we can only solve - 12u+13=8w-3 for w in terms of u.

Adding 3 to both sides, we get - 12u+13=8w-3 = > - 12u+16=8w, or

8w = - 12u + 16

Reduce this by dividing all three terms by 8:

w = (-12/8) u + 2

... and then reduce the fraction: w = (-3/2) u + 2
