8 0

Answer:

Step-by-step explanation:

(3a+8)+(60-a)+(4a-38)=180

combine like terms, 6a+30=180

inverse operation to isolate the variable, 6a=150

divide six on both sides, a=25

replace a in every expression, 3(25)+8=83

60-25=35

4(25)-38=62

83 is biggest out of the three, therefore 83 is the answer.

Solve the system by the elimination method.
2a + 3b = 6
5a + 2b - 4 = 0

multiply thru the top equation by 2
Multiply thru the bottom equation by 3

4a + 6b = 12
15a+ 6b = 12

Subtract and solve for "a":
11a = 0
a = 0

Solve for "b" using 2a + 3b = 6
2*0 + 3b = 6
b = 2
