What is the y-intercept in this linear equation 7y plus 3x - 21 equals 0?
7y+3x-21 =0 7y = -3x+21 y = -3/7x+3 The y intercept is 3
What is 7y-7y equals 5x plus 12-4x?
It's a peculiar, and relatively trivial, linear equation in 'x'.7y - 7y = 5x + 12 - 4xThe left side of the equation is obviously zero.Combine like terms on the right side:0 = x + 12Subtract 12 from each side:-12 = x
How do you solve x-7y equals 18 2x-7y equals 22?
x - 7y = 18 ... (A) 2x - 7y = 22 ... (B) Equation (B) - equation (A) gives x = 4 Substituting this value of x in equation (A) gives 4 - 7y = 18 or 7y = -14 which gives y = -2 Solution: (x, y) = (4, -2)
What is 7y-8 equals 2y plus 37?
It's a simple linear equation in 'y'.To find the solution:7y - 8 = 2y + 37Subtract 2y from each side of the equation:5y - 8 = 37Add 8 to each side:5y = 45Divide each side by 5:y = 9
What is the standard form of the linear equation 8x plus 2 equals 7y?
8x - 7y + 2 = 0 The slope-intercept form is NOT the standard form. The above form is easily generalised to 3 (or more) dimensions, not so with the slope-intercept form.
What is the y-intercept in this linear equation 7y plus 3x - 21 equals 0?
7y+3x-21 =0 7y = -3x+21 y = -3/7x+3 The y intercept is 3
How do you solve the equation x-7y equals 3?
One linear equation in two variables cannot be solved. You can only express one of the variables in terms of the other.
What is 7y-7y equals 5x plus 12-4x?
It's a peculiar, and relatively trivial, linear equation in 'x'.7y - 7y = 5x + 12 - 4xThe left side of the equation is obviously zero.Combine like terms on the right side:0 = x + 12Subtract 12 from each side:-12 = x
What is the answer to -9x-7y equals -2?
There are infinitely many solutions. One linear equation in two variables cannot be solved to give a single answer.
How do you solve x-7y equals 18 2x-7y equals 22?
x - 7y = 18 ... (A) 2x - 7y = 22 ... (B) Equation (B) - equation (A) gives x = 4 Substituting this value of x in equation (A) gives 4 - 7y = 18 or 7y = -14 which gives y = -2 Solution: (x, y) = (4, -2)
What is the slope of 2x-7y equals 14?
2x-7y=14 2x-14=7y from this equation the slope is 2/7
What is 7y-8 equals 2y plus 37?
It's a simple linear equation in 'y'.To find the solution:7y - 8 = 2y + 37Subtract 2y from each side of the equation:5y - 8 = 37Add 8 to each side:5y = 45Divide each side by 5:y = 9
What is the standard form of the linear equation 8x plus 2 equals 7y?
8x - 7y + 2 = 0 The slope-intercept form is NOT the standard form. The above form is easily generalised to 3 (or more) dimensions, not so with the slope-intercept form.
What are the ordered pair to equation x plus 7y equals 33 and equation 3x-2y equals 7?
x = 5 and y = 4
What is 7y equals 33-4y?
7Y = 33-4Y ( add 4Y to both sides of equation ) 11Y = 33 ( divide both sides of equation by 11 ) Y = 3
What is the variable in this equation 7y plus 10 equals -6 plus 14?
y is the variable
How do you solve this linear equation 4x-7y equals -4 x plus y equals 0?
4x-7y = -4 4(x+y = 0) Mutiply all terms in the bottom equation by 4: 4x-7y = -4 4x+4y = 0 Subtract the bottom equation from the top equation: -11y = -4 Divide both sides by -11 remembering that a minus divided into a minus becomes a plus: y = 4/11 Substitute the value of y into the original equations to find the value of x: Therefore: x = -4/11 and y = 4/11
