Answer:
x = -5
Step-by-step explanation:
Start by adding the 5x to each side of the equation to the left to get...
-25 = 5x + 25 + 5x
Then you would add 25 to each side of the equation to get...
0 = 10x + 25 + 25
Adding on, you would simplify this step to get...
0 = 10x +50
You would now have to make the x variable on one side alone so you would subtract 50 from both sides of the equation again to get...
-50 = 10x
Finally you would divide both sides of the equation by 10 to get x alone...
-50/10 = 10x/10
And simplify that to get...
x = -5

Answer:
J + 9 = 63
Jackson = 54 inches
Step-by-step explanation:
Using the variable 'J' for the height of Jackson, we know that Elliott is Jackson's height, plus an additional 9 inches. Since Elliott is 64 inches tall in total, we can add Jackson's height plus 9 to get Elliot's height:
Jackson's height + 9 inches = Elliot's height
J + 9 = 63
Subtract '9' from both sides: J + 9 - 9 = 63 - 9 or J = 54
So, Jackson is 54 inches tall.
