The answer is the letter d the anwer is 30 I think it was just a guess and I'm bored dont throw no hate comment cuz I'm from Newark run my 30 just like the answer 30
With an equation you must isolate x or whatever the variable is. Operations are the things used to make the difference like +,-,x,/.
A great example of this is the following
4x-12=0
First add 12 to both sides making the equation go to
4x=12
now divide 4 from both sides making
x=3
Answer:
When you solve systems with two variables and therefore two equations, the ... of any variable is 1, which means you can easily solve for it in terms of the other ... In the substitution method, you use one equation to solve for one variable and ... Look for a variable with a coefficient of 1 … that's how you'll know where to begin.
Step-by-step explanation:
Answer:
The solutions are x = -1/2 and x = 1/2
Step-by-step explanation:
(2+4x)(2-4x)
We can use the zero product property to solve this
(2+4x)(2-4x)=0
The we set each term = 0
2+4x =0 2-4x =0
Subtract 2 from each side
2-2+4x = 0-2 2-2-4x = 0-2
4x = -2 -4x = -2
The divide the left equation by 4 and the right equation by -4
4x/4 = -2/4 -4x/-4 = -2/-4
x = -1/2 x = 1/2
The solutions are x = -1/2 and x = 1/2
