You Must Solve For The Value Of X To Make The Equation True.
So, There Are Two Ways We Could Try This:
Guess And Check
Or
Solve
I Am Going To Show You How To Solve This Because That Is What You Need To Know. So, We First Need To Look At It.
6x + 3 = 2x + 8
So, we need to subtract 3 from the right side's 8 to begin.
The equation becomes:
6x = 2x + 5
Now, We Need To Simplify The 2x. Subtract 2x from 6x.
The Equation Becomes:
4x = 5
Now, Divide.
4x/4 = 1x = X
So,
X = 5/4
5/4 = 1 and 1/4
So
X = 1 ¼
The difference between the coefficients 7 and 3 is 4, so one solution is
y = 1, x = -1.
Then the remaining solutions will be of the form
x = -7n-1
y = 3n+1
for some integer n.
_____
Some of the solutions are (for n=0, -1, -2, 1, 2)
(x, y) = (-1, 1), (6, -2), (13, -5), (-8, 4), (-15, 7)
Answer:
x = 5
Step-by-step explanation:
You have a right triangle, so you can use the Pythagorean Theorem.
a^2 + b^2 = c^2
x^2 + 12^2 = 13^2
x^2 + 144 = 169
x^2 = 25
x = 5
Answer: x = 5
Answer:
B it seems like it's the most suitable answer
