7(x + 3 ) = 6 - (-7x - 15)
Apply the distributive rule to remove parentheses.
7x + 21 = 6 + 7x + 15
Right away, you should be able to see that 7x will be cancelled rendering this equation to have no solution.
Answer: NO SOLUTION
Answer:
5x-4=11
Step-by-step explanation:
so you multiply 5 times x (a number) and subtract 4 and it equals to 11
Divide both sides by 2
2t/2 = 10/2
t=5
Answer:
23/1 or 23 is the area.
Step-by-step explanation:
in the photo below
Eloise made these steps well:
Square root of negative 2x plus 1 - 3 = x
Square root of negative 2x plus 1 - 3 + 3 = x + 3
The error comes in the next step:
Square root of negative 2x plus 1 = x + 3
Square root of negative 2x plus 1 -1 = x + 3 - 1
Square root of negative 2x = x + 2
the number one is inside the root, therefore they can not be subtracted.
answer
error in the step:
Square root of negative 2x = x + 2
