To solve the equation, it is necessary to isolate the unknown variable "x" first. This is done as shown below:
2x - 3 = 15
Adding 3 to both sides of the equation:
2x - 3 + 3 = 15 + 3
2x = 18
Dividing 2 from both sides:
2x/2 = 18/2
x = 9
Among the choices, the correct answer is B.

Answer:
x=30 cm
y=24 cm
Step-by-step explanation:
y=24 cm
x=√(24²+18²)=√[6²(4²+3²)]=6√(16+9)=6√25=6×5=30 cm
