Answer:

Step-by-step explanation:

b(a + 1) + a = b*a + b + a = ab + b + a

1) b(2a +1 ) = b*2a + b*1 = 2ab + b Not equivalent.

2)a + (a +1)*b = a + ab+ b Equivalent

3) (a +1)(b+ a) = a*(b +a) + 1*(b+a) = ab+ a² +b + a Not equivalent.

4) (a + 1)b + a = ab+ b + a Equivalent

5) a + b(a+1) = a +ab + b Equivalent

6) a + (a +1) + b = a + a + 1 + b = 2a + 1 +b Not equivalent.

7) a(b +1) + b = ab + a + b Equivalent

What is the answer to 6(1+8n)=-39+3n

MissTica

For this case we must simplify the following expression:

$6 (1 + 8n) = - 39 + 3n$

We apply distributive property on the left side of the equation:

$6 * 1 + 6 * 8n = -39 + 3n\\6 + 48n = -39 + 3n$

We subtract 3n from both sides of the equation:

$6 + 48n-3n = -39\\6 + 45n = -39$

We subtract 6 from both sides of the equation:

$45n = -39-6\\45n = -45$

We divide between 45 on both sides of the equation:

$n = \frac {-45} {45}\\n = -1$

Answer:

$n = -1$
