Answer:
x=3
Step-by-step explanation:
You add the eight to both sides, leaving x on the left and making the -2 a 6 on the right.
Now you have x= 3x-6
Add the six to the right, giving you 6+x=3x
Subtract the x from the left and right. you get 6=2x
Divide 6 by 2 to get x.
Solution: (3x + 4y - 3z) x (3x + 4y + 3z)
The answer is would have to be b.
Assume that the number is n.
sum of twice the number and 15 means that you will first multiply the number by 2 then add 15.
the equation us:
2n + 15 = -42
2n = -42-15
2n = -57
n = -28.5
Answer:
3y + 5x = 0
Step-by-step explanation:
The slope of the line = (y2-y1) / (x2-x1) = (5-0)/(-6-(-3))
= 5 / -3 = -5/3
Using the point-slope form , the line that passes through the origin and parallel to this line is
y - 0 = -5/3(x - 0)
y = -5/3 x
Multiply through by 3:-
3y = -5x
5x + 3y = 0
