A + s = 480......s = 480 - a
8a + 5s = 2892

8a + 5(480 - a) = 2892
8a + 2400 - 5a = 2892
8a - 5a = 2892 - 2400
3a = 492
a = 492/3

Z + 6 over 3 = 2z over 4

Black_prince [1.1K]

$\frac{z + 6}{3}$ = $\frac{2z}{4}$ Multiply both sides by 3
z + 6 = $\frac{(3)2z}{4}$ Multiply both sides by 4
(4)z + 6 = (3)2z Simplify
4z + 24 = 6z Subtract 4z from both sides
24 = 2z Divide both sides by 2
12 = z Flip the sides to make it easier to read
z = 12
