Question

if a+3b=5,c=3, then a+3(b+c)=

Answer 1

Answer:

14

Step-by-step explanation:

Let's simplify a+3(b+c).

a + 3b + 3c.

We know that c = 3 so 3c will turn into 9.

3 x 3 = 9

Remove 3c and add 9 to the expression.

a + 3b + 9.

In the first equation, it says a + 3b = 5.

In the expression we are trying to solve, there is an " a + 3b " so you can convert that into 5

Remove a +3b and add 5 to the expression.

5 + 9

Now we can solve the expression.

5 + 9 = 14
