Answer:
Step-by-step explanation:
Lets focus on the third equation to find a:
50 - 2a = 1
Add 2a to both sides of the equation:
50 - 2a + 2a = 1 + 2a
50 = 1 + 2a
Subtract 1 from both sides of the equation:
50 - 1 = 1 + 2a - 1
49 = 2a
Divide both sides by 2:
Now substitute in the know a variable into the first equation:
Add 3b to both sides:
Add 5 to both sides:
54 = 3b
Divide both sides by 3:
c cannot be solved as there is no c variable.
