Answer:
x=-1
Step-by-step explanation:
3x+7=7x+8-3x
3x+7=4x+8
-4x -4x
-x+7=8
-7 -7
<u>-x=1</u>
-1
x=-1
6x+5-3y
Replace for x and y;
6(-2)+5-3(3)
=-12+5-9
=-12-9+5
=-21+5
=-16
Point E is correct answer
Answer:

Step-by-step explanation:






The gradient of the line is -2/3 so A is incorrect
The line is solid so is part of the solution set so the equation needs >= so C and D are incorrect.
The correct answer is B y >= -2/3x + 1
You could have tested the labelled points and any point off the line (say (0,0)) by substituting into each option.
