To solve for d, it is important to remember that we can only add or subtract like terms. Also, that we have to isolate the variable should be solved to one side and all others to the other side. We do as follows:
<span>−2/3x 3/8x = −7/12−1/4x
</span><span>−2/3x 3/8x = −7/12−1/4x
1/4x = </span> −7/12−1/4x
1/2x = -7/12
x = -7/6
Answer:
Step-by-step explanation:
The equation of a line
y = mx + c
y - intercept point y
m - slope of the line
x - intercept point x.
c - intercept of the line
Step 1: find the slope
m = y2 - y1 / x2 - x1
Given two points
( -7 , -7) ( -7 , 4)
x1 = -7
y1 = -7
x2 = -7
y2 = 4
Insert the values into the equation
m = 4 - (-7) / -7 -(-7)
m = 4 + 7 / -7 + 7
m = 11/ 0
Step 2: sub any of the two points given into the equation
y= mx + c
y = 11/0x + c
(-7 ,4 )
x = -7
y = 4
4 = 11/0(-7) + c
4 = -77/0 +c
-77/0 is math error which means that the points are not correct
