Studdy Solution
Solve the system of equations to find the number of employees in each branch.
First, solve the equation 2x=3y 2x = 3y for x x : x=32y x = \frac{3}{2}y
Substitute x=32y x = \frac{3}{2}y into the second equation: 4(32y18)=5(y+18) 4\left(\frac{3}{2}y - 18\right) = 5(y + 18)
Simplify and solve for y y : 6y72=5y+90 6y - 72 = 5y + 90 6y5y=90+72 6y - 5y = 90 + 72 y=162 y = 162
Now, substitute y=162 y = 162 back into x=32y x = \frac{3}{2}y : x=32×162 x = \frac{3}{2} \times 162 x=243 x = 243
The initial number of employees in Branch I was 243 \boxed{243} and in Branch II was 162 \boxed{162} .
