So, 3.05 is NOT the solution
If you would like to know in which step did the student first make an error and what is the correct step, you can calculate this using the following steps:
3(2x - 4) = 8 + 2x + 6
6x - 12 = 8 + 2x + 6
6x - 12 = 14 + 2x ... Step 2
6x - 2x = 14 + 12
4x = 26
x = 26/4 = 13/2
The correct result would be Step 2; <span>6x - 12 = 14 + 2x.</span>
we are given
Firstly, we will simplify left side
and then we can solve for k
Left side is
we can arrange like terms
now, we can use property of exponent
now, we can equate it with right side
and we get
We can see that both sides have 30 , a and b
and they are equal
so, exponent of a must also be equal
now, we can solve for k
................Answer
Step-by-step explanation:
(-7)+(-6)+(-1)=-14
(-14)-3=-11
-11÷7=-1.5714285714286 or -2 if you round too the tenths place
