Answer: All you have to do is think to yourself it’s 2 out of 3
Step-by-step explanation:
Do you know what n equals so i can solve it?<span />
Answer:
D
Step-by-step explanation:
1. Make it into a y = x equation
y = 9x +7
2. change x to y and y to x
x = 9y + 7
3. Isolate y ( if not possible, use implicit differentiation but here you can)
x-7 = 9y
1/9x-7/9 = y
Answer:
x=5
Step-by-step explanation:
If the equation is:
3(x+1)=7(x-2) -3
Solution:
Multiply (x+1) by 3 and (x-2) by 7
3x+3 = 7x-14 -3
3x+3 = 7x -17
Now combine the like terms:
3+17 = 7x-3x
20 = 4x
Now divide both the terms by 4
20/4 = 4x/4
5 = x
You can write it as x=5
Thus the value of x is 5 ....
