Question

A+A=2
A + B=3
A+B+C=6
A + B +CX4 = ?​

Answer 1

Answer:

15

Step-by-step explanation:

A + A = 2

2A = 2

A = 1

A + B = 3

1 + B = 3

B = 3 - 1

B = 2

A + B + C = 6

1 + 2 + C = 6

C = 6 - 3

C = 3

We have to find the value of A + B + 4C.

Simply substitute the values which we get from above calculations in A + B + 4C.

→ 1 + 2 + 4(3)

→ 3 + 12

→ 15

Hence, the value of A + B + 4C is 15.

Answer 2

A+A=2
2A=2
A=1

A+B=3
Substitute A=1 in A+B=3
1+B=3
B=2

A+B+C=6
Substitute A=1 ; B=2 in A+B+C=6
2+1+C=6
3+C=6
C=3

But they given, A+B+C x 4= 1+2+3 x 4
=3x4
=12.

Hope this answer will help u ☺️
