Solve the following system of equations by substitution<br> 2x – 3y = -1<br> y = x - 1
Aliun [14]

Answer:

(4, 3)

Step-by-step explanation:

Plug in x - 1 where y is. The equation will turn in 2x - 3(x - 1) = -1. Distribute, and you'll have 2x -3x + 3 = -1. Combine like terms (2x and -3x) and you'll have -x + 3 = -1. Subtract 3 from both sides, and you'll have -x = -4. Divide by -x (or -1) on both sides, and you'll have x = 4. Since y = x - 1, y = 3, since 4 - 1 = 3. Sorry if this sounds repetitive btw. Good luck :D

I have a project, im gonna have to teach someone how M and B in the equation y=mx+b affect the equation of the line.
Luba_88 [7]
Y = mix + b would be slope intercept for. your y intercept would be B which is the line that crosses that y intercept your Mx would be a fraction for point slope form like if your slope would be 1 over 2 you would fo up and left twice because of rise over run

2/3y + 15 = 9 <br> What are the steps for this question
xenn [34]

Answer:

see below

Step-by-step explanation:

2/3y + 15 = 9

Subtract 15 from each side

2/3y + 15-15 = 9-15

2/3y = -6

Multiply each side by 3/2 to isolate y

3/2 * 2/3y = -6 *3/2

y = -9
