Answer:

63

Explanation:

Set up the proportion

(6x+3)/17 = (8x - 1)/21 Cross Multiply

21 * (6x + 3) = 17 (8x - 1) Remove the brackets

126x + 63 = 136x - 17 Subtract 126x from both sides

63 = 136x - 126x - 17 Combine

63 = 10x - 17 Add 17 to both sides

63 + 17 = 10x Combine the left

80 = 10 x Divide by 10

80/10 = x

x = 8

Now you want 8x - 1

8*8 - 1 = 63
