Due to the limitations of Answers, certain symbols cannot be written in questions; in particular this includes most punctuation which includes equals (=).
It is better to write all mathematical symbols as words
We suspect you meant: y - 3 = 2(x - 7)
In which case the equation is y = 2x- 11
7-3(4-2x)-10x 4(4)-2x)-10x 16-8x-10 16-18x
It is 3 - 14x
-5
y-y1=m(x-x1) y-7=2(x-3) y-7=2x-6 y=2x-1 y=2x-1
You are looking for the solution to the function 2x - 3y = 7.This means that when you substitute 5 for x and 1 for y, the equation makes sense logically.(2*5) - (3*1) = 10 - 3 = 7.This makes sense logically.
2x+7=3 is an equation. However, 2x=-4 is equivalent. So is x=-2. And an infinite number of others.
2x + 3 = 4x - 7 <=> 4x - 7 = 2x + 3 <=> 2x = 10 <=> x = 5 - - - 2x + 3 = 4x - 7 Take the 2x from each side of the equation. 3 = 2x - 7 Get the numerals together 7 + 3 = 2x Therefore 10 = 2x Therefore 5 = x
2x + 3 = 72x = 4x = 2
The equation would be 2x+3=10 The first step is to subtract 3 from each side then you will have 2x=7 then you would divide 7 by 2 and you would get 3.5 so x= 3.5 here are the steps written as an equation then being solved. 2x+3=10 -3 -3 2x=7 7/2= 3.5 x=3.5
im assuming your equation is 2x + 1 = 7 in this case you need to find what x equals 2x + 1 = 7 2x + 1 - 1 = 7-1 2x = 6 x = 3 put it back into the equation to check if your answer is correct 2(3) + 1 = 7 6 + 1 = 7 7 = 7 Correct! if your equation is 2x - 1 = 7 x = 4 check it 2(4) - 1 = 7 8 - 1 = 7 7 = 7 Correct! if your equation is 2x1 = 7 x = 7/2 check it 2(7/2)1 = 7 2(7/2) = 7 2 * 7 / 2 = 7 14/2 = 7 7 = 7 Correct! hope i got your equation right. if not you can message me on my message board to get more help.
-2x - 3 = 7 1) For this equation, you first add 3 to both sides. -2x = 10 2) Then, you divide both sides by -2. x = - 5 The answer is x = -5
7-3(4-2x)-10x 4(4)-2x)-10x 16-8x-10 16-18x
(2x - 10) + 7 = 52x - 3 = 52x = 8x = 4
Yes.
Line segment: (3, 5) and (7, 7) Midpoint: (3+7)/2, (5+7)/2 = (5, 6) Slope or gradient: (7-5)/(7-3) = 1/2 Perpendicular slope = -2 Equation: y -6 = -2(x-5) => y = -2x+10+6 => y = -2x+16 So the perpendicular bisector equation is y = -2x+16
Points: (1, 3) and (3, 7) Slope: 2 Equation: y = 2x+1
It is 3 - 14x
