See each answer below.
1) If we subtract 7 from both sides and try to take the square root, we are taking the square root of -7. Therefore, there are no solutions.
2) Dividing by 3 and taking the square root gives an answer of 0.
3) Add 4, multiply by 4 and finally take the square root of each side.You will get positive or negative four.
4) Divide by 4 and then take the square root. You have positive or negative 5/2.
Answer:
1/2
Step-by-step explanation:
Answer:
-6
Step-by-step explanation:
firstly arrange whole equation,
-2x+7=19
Now, Transpose 7 to RHS (right hand side)
-2x=19-7
-2x=12
Further, seperate coefficient -2 from x
and transpose it to RHS and divide them
x=12/-2
Hence, x= -6
You want to isolate the variable 'y'.
Subtract 10 to both sides:
Divide -3 to both sides:
