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!
Angle 1 and 3 are equals and 2 and 4 are the same
Answer:
Using division equality property to solve for b. b=27
Step-by-step explanation:
A book cost $3
Mr. Grayson spent $81 on books
Let number of books be b
Total cost invest on book = 3b
This would be equal to $81
Therefore, 3b=81
Now we solve for b
Using division method of equality
If we divide both side by same number in equality.After division we get both are equal .
3b=81
Here we divide by 3 both sides
3b÷3=81÷3
b=27
Thus, Using division equality property to solve for b. b=27
If the answers are in the standard form of a line then it would be -x + (-3x) = -5y. This is because the standard form of a line is written as Ax + Bx = Cy
