Answer:
hope that helps :))
Step-by-step explanation:
Step 1: Subtract 12c from both sides.
12c+12−12c=12c+9−12c
12=9
Step 2: Subtract 12 from both sides.
12−12=9−12
0=−3
Answer:
x = 13.5 and y = 7
Step-by-step explanation:
Given equations are :
x + y = 20.5 ...(1)
x − y = 6.5 ...(2)
Add equation (1) and (2).
x + y + x- y = 20.5+6.5
2x = 27
x = 13.5
Put the value of x in equation (1).
13.5 + y = 20.5
y = 20.5-13.5
y = 7
Hence, the values of x and y are 13.5 and 7.
