Could someone please help me with this thank you very much
elena-s [515]

Answer:

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 <em>B</em><em> </em>was substituted into equation <em>A</em><em>.</em>

<em>equ. \: a = (2x - 3y = 7) \\ equ. \: b = (x = 1 - y)</em>

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

ANEK [815]
A number is multiplied by 8 and the result is 28.

A number= x.

8(x)= 28

Divide both sides by 8.

28/8= 3.5

x= 3.5
