Answer:
2x - y = -7
Step-by-step explanation:
The equation y = 2x+7 needs to be written in standard form 
where A must be positive.
To convert to standard form, subtract 2x from both sides.
-2x + y = 7
Multiply each term by -1.
-1(-2x + y =7)
2x - y = -7
Answer:
x = - 
Step-by-step explanation:
Given
- 2(4x + 3) = 3(x + 1) ← distribute parenthesis on both sides
- 8x - 6 = 3x + 3 ( subtract 3x from both sides )
- 11x - 6 = 3 ( add 6 to both sides )
- 11x = 9 ( divide both sides by - 11 )
x = -
