Solving systems of equations algebraically.
Elanso [62]

Answer:

x = 2

y = -1

Step-by-step explanation:

Since it gives you the value of y already, just plug that into the equation, like so:

y = 4x - 9

x - 3 = 4x - 9

<em><u>Subtract the x from both sides:</u></em>

x - 3 = 4x - 9

-x       - x

__________

-3 = 3x - 9

<em><u>Then, add 9 to both sides:</u></em>

-3 = 3x - 9

+9        + 9

________

6 = 3x

<em><u>Divide both sides by 3:</u></em>

2 = x

<em><u>Now plug in x for y:</u></em>

y = x - 3

y = 2 - 3

y = -1

NEED ANSWER FAST!<br> what is the value of X?

<span>Angles on one side of a straight line always add to 180°.

Look at the picture.

a = 180° - 134° = 46°
b = 180° - 130° = 50°

</span><span>In a triangle, the three interior angles always add to 180°.

a + b + c = 180°

c = 180° - (46° + 50°) = 180° - 96° = 84°

x° = 180° - 84° = 96°

</span>
<span>We can see that:
x = a + b
