Answer: 6 = - 2.

Step by step explanation:

Subtract 4b from 7b.

3b + 3 = 3 - 3 (b+4)

Simplify 3 - 3 (b+4).

3b + 3 = - 3b - 9

Move all terms containing b to the left side of the equation.

6b + 3 = - 9.

Move all terms not containing b to the right of the equation.

6b = - 12

Divide each term by 6 and simplify.

And, voila! You have your answer, 6 = - 2.

damaskus [11]

Answer:

Alyssa had scored 3 goals today.

Step-by-step explanation:

Given:

Number of goals scored yesterday = $x$

Total number of goals scored in 2 games = 4

We need to find the number of goals scored today.

Solution:

Now Given:

Today she scored 3 times as many goals than yesterday.

So we can say that;

Number of goals scored today = $3x$

Now we know that;

Total number of goals scored in 2 games is the sum of Number of goals scored yesterday and Number of goals scored today.

framing in equation form we get;

$x+3x=4\\\\4x=4$

Dividing both side by 4 we get;

$\frac{4x}{4} =\frac{4}{4}\\\\x=1$

Number of goals scored yesterday = 1

Number of goals scored today = $3x = 3\times1 =3$

Hence Alyssa had scored 3 goals today.
