Answer:

6\frac{1}{3}

Step-by-step explanation:

4x-12 = x+7

4x-12+12 = x+7+12

4x = x+19

4x-x = x+19-x

3x=19

x = 6\frac{1}{3}

And if we substitute the value of x into the equation 4x-12 = x+7,

we will get 13\frac{1}{3} = 13\frac{1}{3} in the end.

Hope this helps :)

I NEED HELP PICTURE PROVIDED!
Sav [38]
Question 2:
The answer is 21
The two angles are vertically opposite, which makes them equal and also means we can make an equation:
4x - 4 = 3x + 17
- 3x
x - 4 = 14
+ 4
x = 21

Question 3:
The answer is 23
Again, the angles are vertically opposite, so we can make them equal each other:
5x - 53 = 3x - 7
- 3x
2x - 53 = -7
+ 53
2x = 46
÷ 2
x = 23

I hope this helps!
