Answer for #10:

$y = 2 \: and \: x = 1$

Answer for #1:

$x = 2 \: and \: y = - 1$

Step-by-step explanation:

In order to solve a simultaneous equation using the substitution method you have to:

Use one of the equation and substitute it into the other equation, in this case equation B was substituted into equation A.

 $equ. \: a = (2x - 3y = 7) \\ equ. \: b = (x = 1 - y)$ 

Therefore since x = 1 - y, equation A would be:

$2(1 - y) - 3y = 7 \\ (2 - 2y) - 3y = 7 \\ - 2y - 3y = 7 - 2 \\ - 5y = 5 \\ y = - 1 \: and \: x = 2$

Solve the system of equations x + y = 0 and x + 9y= -48 by combing the eqatuons

lidiya [134]

Answer:

x = 6

y = -6

Step-by-step explanation:

x + y = 0 (Multiply by -1)

x + 9y= -48

-x - y = 0

x + 9y= -48

8y = -48

y = -6

x + y = 0

x - 6 = 0

x = 6

Artemon [7]

Answer:

y=8

Step-by-step explanation:

Point slope is y2-y1 over x2-x1

So its 8-(-6) over 8-8 which equals 14/0 which means the equation of the line is y=8

This is a horizontal line on 8 on the y axis
