Answer: x=7/2, x=-3
Step-by-step explanation:
First lets do look at it without the absolute value marks
4x-1=13
4x=14
x=7/2
Now lets do the same but assume 13 is negative,
4x-1=-13
4x=-12
x=-3
It should look like a vertical line on the 2 of the x axis and everything to the right would be shaded.
Answer:
x = -11 and y= -8 is the solution to the system
Step-by-step explanation:
Given:
x - 2y = 5 let it be equation (i)
-x + y = 3 let it be equation (ii)
To find:
x = ?
y = ?
Solution:
The equations are given to us from which we are supposed to find the values of x and y
Taking first equation which is
x - 2y = 5
adding 2y on both sides
x - 2 y + 2y = 5 + 2y
x = 5 +2y ............................(iii)
Now putting this value in equation (ii)
which is
-x + y = 3
Putting value gives
-(5 + 2y) + y = 3
-5 -2y+y = 3
-5 - y = 3
adding 5 on both sides
-5 -y + 5 = 3 + 5
-y = 8
Multiplying both sides by (-1)
-y(-1) = 8 * (-1)
y = -8
Now we have equation (iii) which is
x = 5 + 2y
putting the value of y in it
x = 5 + 2*(-8)
x = 5 -16
x = -11
so the solution to the system is
x = -11 and y= -8

Answer: h= 5/4
Step-by-step explanation:
h - 1/2 = 3/4, to find the value of h:
Step 1: Add 1/2 to both sides of the equation
h = 3/4 + 1/2 (findthe common denominator
h = 5/4
