Answer:
21/29
Step-by-step explanation:
Let the two numbers be x and y.
Given,
x + y = 23
x = 23 - y
Also given,
y = 2x - 1
y= 2(23 -y) -1
y = 46 - 2y - 1
3y = 45
y = 15
x = 23 - y = 23 - 15 = 8
Hence, the two numbers are 15 and 8.
By estimating. 5x700 is 3500. i multiplied the first digits in the equation.
