Answer:

The answer to your question is x = -3

Step-by-step explanation:

Equation 4 - (x + 1) = 6

- Subtract 4 in both sides

4 - (x + 1) - 4 = 6 - 4

- Simplify

- (x + 1) = 2

- Remove parentheses

- x - 1 = 2

-Add 1 to both sides

-x - 1 + 1 = 2 + 1

- Simplify

- x = 3

-Divide both sides by - 1

- x / -1 = 3 / - 1

- Simplify

x = -3

Answer:

Step-by-step explanation:

The negative in front of the parenthesis changes the signs of the numbers and variables inside the parenthesis. We can rewrite as

4 - x - 1 = 6 and

3 - x = 6 so

- x = 3 and

x = -3

Solve the triangle give the measure of angle G

zalisa [80]

Answer:

G = 46 degrees

Step-by-step explanation:

Here, we want to find the measure of angle G

Mathematically, as we can see, what we have is a right triangle

For a right triangle , the sum of angles is 90 degrees

Thus, if we add the two internal angles, we get 90 degrees

Hence;

44 + G = 90

G = 90-44

G = 46 degrees
