Answer:
x = 1
Step-by-step explanation:
There are a couple of ways to solve this. One is to graph the left side of the equation, graph the right side of the equation, and look for the point where those graphs intersect. It is at x = 1. The first attached graph shows this solution.

Another method for solving such an equation is to subtract one side from the other and look for the value of x that makes the resulting expression zero.
(-2x +3) -(-3(-x) -2) = 0
A graphing calculator doesn't need to have this simplified. If it is simplified, it becomes ...
-5x +5 = 0
So, the graphed line is y = -5x+5. Its x-intercept is x=1, the solution of the original equation. The graph of this is shown in the second attachment.
Answer:
A. 8 rows.
B. 3 toy soldiers.
Step-by-step explanation:
We are told that Meliza has 43 toys soldiers, she line them up 5 to fight imaginary zombies .
A. Let us find the greatest multiple of 5 from 43.
Multiples of 5 are: 5,10, 15, 20, 25, 30, 35, 40, 45,..
We can see the greatest multiple of 5 from 43 is 40.
Let us divide 40 by 5 to find the number of rows that Meliza can make.
Therefore, Meliza can make 8 rows of 5 from 43 toy soldiers.
B. To find the number of soldier in last row we will subtract 40 from 43.
Therefore, the number of toy soldiers in last row will be 3 soldiers.
