Answer:
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
