3 + 12 (y-4) = 40
*Use distribution*
3 + 12y - 48 = 40
*combine like terms*
-45 + 12y = 40
* what you do to one side of the equation you have to do to the other side
-45 +12y = 40
+45 +45
-----------------------
12y = 85
*now you divide to isolate variable*
85
------- = 7
12
Y =7
Answer:
15 and 16
Step-by-step explanation:
the square root of 253 is about 15.91
The first one is A and the second one is C
From the equation solved, it can be deduced that the value of x will be -5.
<h3>How to solve an equation</h3>
From the information given, the equation is 4x/7 - 6 = -20. The step to solve it is given below:
4x/7 - 6 = -20
Cross multiply
4x = -20(7 - 6)
4x = -20(1)
4x = -20
Divide both side by 4
4x/4 = -20/4
x = -5
In conclusion, the value of x is -5.
