1.
Calculate 250 x (1 - 63 %) = 250 x 37 % = 92.5

or

2.
% remaining is 100 - 63 = 37
so 37% is 37/100
37% of 250 = 250 x 37 / 100 = 92.5

Distribute the 2 through the parentheses —> 2u+6v = w-5u

2. Subtract 2u from both sides —->  6v = w-7u

3. Subtract w from both sides —->  6v-w = -7u

4. Divide both sides by -7 —–> (6v-w)/-7 = u

u = (w-6v)/7

2/3q + 5 = 3/4
2/3q + 5 - 5 = 3/4 - 5
2/3q = -17/4
2/3q (3/2) = (-17/4)(3/2)
q = -51/8

or

first divide each side by 4:
(y+3) = 6/4
Now subtract 3 from each side:
y = -6/4 +3
y = -6/4 + 12/4
y = 6/4 = 3/2
