2x-y=-1 3x-y=2 in simultaneous equations

zloy xaker [14]

Answer:

Let's solve for x.

2x−y=−13x−y

Step 1: Add 13x to both sides.

2x−y+13x=−13x−y+13x

15x−y=−y

Step 2: Add y to both sides.

15x−y+y=−y+y

15x=0

Step 3: Divide both sides by 15.

15x

x=0

Answer:

x=0

9th grade alg 1 number 43 and work please!

Darya [45]

Answer:

The rule is y = -7x + 5

→ Other values of x;

-9

→ Other values of y;

5
-2
-9
-12
28
68
-170

Step-by-step explanation:

» Take points (1, -2) and (3, -12) from the table.

☑ General equation of a line is y = mx + c

m is the slope
c is y-intercept

✍ For slope, m :

${ \tt{slope = \frac{ - 12 - 2}{3 - 1} }} \\ \\ { \tt{slope = \frac{ - 14}{2} }} \\ \\ { \tt{m = - 7}}$

✍ For y-intercept, c :

${ \tt{y = mx + c}}$

» Taking point (1, -2):

${ \tt{ - 2 = (1 \times - 7) + c}} \\ { \tt{c = - 2 + 7}} \\ { \tt{c = 5}}$

${ \boxed{ \tt{y = - 7x + 5}}}$

Please help, I have redone this problem a million times and i cant get it right. Time sensitive!!

Advocard [28]

Answer:

Step-by-step explanation:

This should be easy one unless you're making silly mistake like forgetting to take reciprocal of $\frac{3}{2x}$

lets do it:

$\frac{x+2}{x-1}$ ÷ $\frac{3}{2x}$ first: we take the reciprocal of 3/2x now its

$\frac{x+2}{x-1}$ * $\frac{2x}{3}$ now just multiply top and bottom by using distributive method

$\frac{2x^2 +4x}{3x-3}$ this is your answer.
