Answer:
v=8
Step-by-step explanation:
Let's solve your equation step-by-step.
16v−9v=56
Step 1: Simplify both sides of the equation.
16v−9v=56
16v+−9v=56
(16v+−9v)=56(Combine Like Terms)
7v=56
7v=56
Step 2: Divide both sides by 7.
7v
7
=
56
7
v=8
hope this helps!
4(x+7) becomes 4x+28 you multipli the 4 in parentheses ans 2(x+7) becomes 2x+14
4x+28=2x+14 you move the x termes to the left and other numbers to the right look:
4x-2x=14-28 when you change the sides always change the sign +or-
2x=-14
2x/2=-14/2
X=-7
Answer:
No solution
Step-by-step explanation:
So we have the equation:

First, subtract 20 from both sides:

Now, we can stop. Recall that absolute value will always <em>always</em> give a positive answer.
Since this equals -16, this means that there is no solution.
And we're done!
