The best method would be to cross-multiply. Multiply the figure on the top left with the bottom right. Then set it equal to the multiplication of the bottom left with the top right.
This would turn into:
-1(x-1)=2(x+3) Then distribute the multiplication through the parentheses.
-x+1=2x+6 Next, get all the variables on one side, and the integers on another.
2x+x=1-6
3x= -5
x= -5/3
Answer:

Answer:
3rd one
Step-by-step explanation:
Answer:
3(x+6)=3x+18 = infinite
x-7=-7+x = infinite
5(x-3)=15+5x = no solution
Answer:
-15/4
C:15/-4
Step-by-step explanation:
a negative number divided by another negative number gives a positive number : -15 / - 4 = +3.75
-15/4 and 15/-4 = -3.75
15/4 = 3.75 (two positive numbers divided with each other yields a positive number)
-4/15 and 4 / -15 = 0.27
