Answer:
x= -2
Step-by-step explanation:
-2x-7=3(4x+7)
multiply numbers in parenthesis by 3
-2x-7=12x+21
move terms
-2x-12x=21+7
subtract -2x to -12x but since there negative the equation is addition. Also, add 21 to 7
-14x=28
divide both sides by -14
x= -2
Answer:
You need to find equation of line containing (1,-3) and (7,15)
First find slope (m) = 15+3)/7-1 = 18/6 = 3
So, eq of line is y +3 = 3( x-1)
y+3 = 3x -3
y-3x +6 = 0
