Question

If a = 5, b = 4, and c = 7, find the value for 3(b + a) = c.
10
15
34
20

Answer 1

20

Explanation:

3 (b + a) = c

3 (4 + 5) = 7

12 + 15 = 7

27 = 7

27 - 7

20

Answer 2

`\huge\boxed{ \sf{Answer}}`

Given,

`a = 5 \\ b = 4 \\ c = 7`

And the equation we need to solve is,

`3(b + a) = c`

To find the answer, you need to substitute the values of a, b & c in the equation.

`3(b + a) = c \\ 3b + 3a = c \\ ( 3 * 4) +( 3 * 5) = 7 \\ 12 + 15 = 7 \\ 12 + 15 - 7 = 0 \\ = 27 - 7 \\ = 20`

↦ The answer is 20.
