Step 1: Simplify both sides of the equation.
x−7=15+3x
x+−7=15+3x
x−7=3x+15
Step 2: Subtract 3x from both sides.
x−7−3x=3x+15−3x
−2x−7=15
Step 3: Add 7 to both sides.
−2x−7+7=15+7
−2x=22
Step 4: Divide both sides by -2.
−2x/−2=22/−2
x=−11
15x-24
the answer is not B because 3*-5= -15, we need -24
the answer is not C because 3*-24= -72
the answer is not A because 5*8= 40
Answer :
D. 3(5x − 8)
(3)(5x)(3)(-8)
15x-24= 15x-24

6×5=30
-6×5=-30
2. For adding negative number to a negative number you just add it on.
Answer:
We cannot have a single point of solution
Step-by-step explanation:
When the boundary lines are parallel, we can have no solution, or infinite solutions. We cannot have a single point of solution
