When solving equations like these, our number one goal is to get x to be alone.
So given the equation lets go through it step by step.
3x - 5 = 10 + 7x (first step is to add 5 to both sides)
+ 5 = + 5 ( Now lets see what we have now)
3x = 15 + 7x ( We need the x to be alone! So lets subtract -7x from both sides.)
-7x = -7x ( now what do we have?)
-4x = 15 (okay divide both sides by 4 to isolate the x)
÷4 = ÷4 (now the 4's on the left side cancel out, and we solve on the right side)
x = 3.75
That's your answer :) Good Luck!
Answer:
-1/3
Step-by-step explanation:
Distribute- 3n-9=-10
Add 9 to both sides- 3n=-10
Divide both sides by 3- n=-1/3
Check- 3(-1/3)-9=-10 (-1)-9=(-10) -10=-10
Answer:
y = -2x+4
Step-by-step explanation:
hope this helps
Option C and D is correct .....
it's a horizontal translation so, the equation is f(x) = (x + 5). Whenever you translate to the right it is negative.
