Answer:
One solution, x=-1
Explanation:
-3x - 15 - 2x = 5(x - 1)
First let’s simply like terms on the left, which will be x
-3x - 2x = -5x
-5x - 15 = 5(x - 1)
And now that the left side is fully simplified, distribute on the right side
5 (x -1) …. 5x - 5
.
-5x - 15 = 5x - 5
But there is x on both side. Let’s move -5x to the other side so we are only solving for one x on a single side.
-15 = 5x - 5
+5x
-15 = 10x - 5
Addition property of equality (Add 5 to solve)
-15 = 10x
+5
-10 = 10x
Division property of equality (divide by 10 to solve)
10/-10 = -1
x = -1!!
