Question

A + A = 30
B + B = 20
C + B = 8
find A + B × C = ?​

Answer 1

Step-by-step explanation:

2A= 30

A= 30÷2

A = 15

2B = 20

B = 20÷2

B=10

C+B = 8

So, we will put the value of B in the place of B.

C+10 = 8

C = 8 - 10

C = (-2)

So, A+B×C =

Now we will put the value.

15+10×(-2)

25×(-2)

-50

Therefore, A+B×C = -50

Note:- Always remember:-

+ × + = +

- × - = +

+ × - = -

Hope it helps you.

Answer 2

Answer:

-5

Step-by-step explanation:

GIVEN:

A+A=30

2A=30

A=15

Also ; B+B=20

2B=20

B=10

SO B+C = 8

THAT IS 10 + C = 8

THEREFORE C = -2

Substituting all values

A+B*C = 15 + 10 * -2

Applying BODMAS RULE

15-20

-5
