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:

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