51(x - 21) = x + 58

Distributive property

51x - 1071 = x + 58

Subtract x from both sides

50x - 1071 = 58

Add 1071 to both sides

50x = 1129

Divide both sides by 50

x = 22.58

Answer:

216 cm³

Step-by-step explanation:

1/3x + 63 = 5/8x

subtract 1/3x from each side; (1/3x = 8/24x and 5/8x = 15/24x)

63 = 7/24x

7x = 63(24)

7x = 1512

x = 216
