Well, let's take a deep breath and look at this equation together. To solve for x and y, we need more information or another equation. This equation alone has multiple solutions without more context, like a second equation or specific values for x or y. Just like painting a beautiful landscape, we need all the colors to create the full picture.
1 + 7y = 5x - 2 7y = 5x - 3 - 5x = - 7y - 3 x = 7/5y + 3/5 ---------------------
5y explanaition 5x-5x=0, 0-2y=-2y, -2y+7y=5y
7y+5=-9... 7y must equal -14 therefore y must be -2
i dont know
10x-7y = -6 5x+7y = 81 Add both equations to eliminate y: 15x = 75 Divide both sides by 15 to find the value of x: x = 5 Substitute the value of x into the original equations to find the value of y: Therefore: x = 5 and y = 8
5x - 7y = 5 (subtract both sides by 5x) -7y = -5x + 5 (divide both sides by -7) y = (5x - 5)/7 If you want to solve for y = 0, then x = 1.
-5x+7y-6z
Combine like terms: -2x - 4y + 5x - 7y = 3x - 11y -2x + 5x = 3x -4y + -7y = -11y
1 + 7y = 5x - 2 7y = 5x - 3 - 5x = - 7y - 3 x = 7/5y + 3/5 ---------------------
Let's explain with an example: 2x - 7y = 11 5x + 7y = 3 To solve this system of equations by elimination we "add" the second equation to the first equation. So basically: 2x + 5x - 7y + 7y = 11 + 3 Which then symplifies to: 7x = 14 and x = 2 Then plug x = 2 into the original equation: 5(2) + 7y = 3 Which leads to: y = -1 So the solution is (2,-1).

Can you help me find the value x & Y 3x + 7y = 5 5x-2y = -19
7y+5=-9... 7y must equal -14 therefore y must be -2
This is a linear equation. You can transform this into the form y = as follows: 5x + 7y = 1500 Subtract 5x from both sides: 5x (-5x) + 7y = 1500 (-5x) 7y = 5x - 1500 Then divide both sides by 7: 7y/7 = (5x - 1500)/7 y = (5/7)x - (1500/7) In order to find the zeros for the equation, you can simply substitute 0 for one variable at a time, and then solve the equation for the other variable. If we set y = 0, 0 = (5/7)x - (1500/7) (1500/7) * (7/5) = x x = 300 So (x = 300, y = 0) is one solution. 5x + 7y = 1500 Substituting 0 for x, we get: 7y = 1500 y = (1500/7) = approximately 214.29 The second solution is (x=0, y=214.29)
5x - 7y = -35At the x-intercept, y=0:5x = -35x = -7At the y-intercept, x=0:-7y = -35y = 5
Slope is found by this form. Y = mX + c ( m = slope ) - 5X - 7Y - 6 = 0 ( I assume this is what you mean ) - 7Y - 6 = 5X - 7Y = 5X + 6 Y = - 5/7X - 6/7 The slope would be in this instance, - 5/7 ----------
5x = 7y , we divide both side by 'y' 5x/y = 7y/y (y will now be deducted) 5x/y = 7 x/y = 7/5 Therefore, x:y = 7:5
