Answer:

x = -6

Step-by-step explanation:

5x + 7 = 3x - 5

Subtract 3x from both sides

2x + 7 = -5

Subtract 7 from both sides

2x = -12

Divide both sides by 2

x = -6

5x+7+5 = 3x add 5 to both sides
7+5 = 3x -5x subtract 5x from both sides
12 = -2x Combine both sides values
2x= -12 Move the negative if u want
X= -6 Divide by 2 to get the solution
5(-6)+7= 3(-6) -5 Make sure it’s right
-30 + 7 = -18 -5 Distribute -6
-23= -23 Check shows it’s correct
