11 + 3x = −15 − 4x
U subtract 11 from both sides 11+3x-11=-15-4x-11
Refine3x=-4x-26
Add 4x to both sides
3x+4x=-4x-26+4x
Refine7x=-26
Divide both sides by 7
<span>7x/7 = -26/7</span>
Refinex= -26/7
Answer: 
Step-by-step explanation:
The equation of the line in Slope-intercept form is:
Where "m" is the slope of the line and "b" is the y-intercept.
Find the slope with this formula:
Given the points (-10,-7) (3,-7), substitute values into the formula. Then:
Substitute the slope and any point into and solve for "b":
Then, substituting "m" and "b" into the equation , you get that the equation of this line is:
I turn the mixed numbers into decimals before doing anything else.
11 2/5----> 57/5----> 11.4
4 2/7----> 30/7----> 4.29
2 1/7----> 15/7----> 2.14
11.4=q-4.29+2.14
11.4=q-2.15
13.55= q
13.55 converted to a fraction is 13 11⁄20
q=13 11⁄20
Answer:
Step-by-step explanation:
5/y + 7/x =24.........(1)
12/y + 2/x =24........(2)
Let 1/y = a and 1/x = b
5a + 7b = 24 ...........(3)
12a + 2b = 24...........(4)
Multiply (3) by 2 and (4) by 7
10a + 14b = 48..........(5)
84a + 14b = 168.........(6)
Substracting (5) from (6)
84a - 10a = 168 - 48
74a = 120
a = 120/74
a = 60/37
Putting a = 60/37 in (3)
5a + 7b = 24
5(60/37) + 7b = 24
300/37 + 7b = 24
Multiply each term 37
300 + 259b = 888
259b = 888 - 300
259b = 588
b = 588/259
And a = 1/y
60/37 = 1/y
Cross multiply
60y = 37
y = 37/60
Also
b = 1/x
588/259 = 1/x
Cross multiply
588x = 259
x = 259/588
