To solve each equation, cross multiply or invert the equation to isolate the variable. The solutions are y = 150, y = 2.35, y = 4.5, and y = 30.
Step-by-step explanation:
To solve the equations, we need to isolate the variable on one side of the equation. Let's solve each equation step by step:
Equation 1:
To isolate y, we'll cross multiply:
6/13 = y/32
Simplifying, we get y = (6/13) * 325 = 150
Equation 2:
Again, cross multiplying:
5/17 = y/8
Simplifying, we get y = (5/17) * 8 = 2.35
Equation 3:
This time, we'll invert the equation:
16/9 = 8/y
Simplifying, we get y = (8 * 9) / 16 = 4.5
Equation 4:
Also by inverting the equation:
15/y = 30/y
Simplifying, we get y = 30
