Which best explains why the equation 7x plus 3 equals 7x plus 3 has infinitely many solutions?
Strictly speaking the above equation is a tautological equation or an IDENTITY. An identity is true for all values of any variables that appear in it. Thus, the above "equation" is true for all value of x. - that is, it has infinitely many solutions.
Is y 7x - 3 a proportional relationship?
If you mean: y=7x -3 then it is a proportional relationship of a straight line equation.
If x 3 the value of 7x - 2x is?
If you mean x = 3 then the value of 7x-2x is 21-6 = 15
X2 plus 7x plus 10 equals?
The value of x2+7x+10 depends on the value of X. If x=1, then x2+7x+10 = 18 If x=2, then x2+7x+10 = 28 If x=3, then x2+7x+10 = 40 and so forth
What is the value of the y variable in the solution to the following system of equations- 3x - 6y equals 3 7x - 5y equals -11?
If "equations-" is intended to be "equations", the answer is y = -2. If the first equation is meant to start with -3x, the answer is y = 0.2
If you have 32 equals -3 minus 7x what should x be so this stament is true?
32= -3 - 7x 32 + 3 = - 7x 35= - 7x 35/7 = -x 5 = -x -5= x
What is 7x plus 3 equals -5 plus 2x plus 18?
It is an equation and the value of x is 2
y 7x plus 10 and you know that y 3 What is the value of x?
The equation y = 7x + 10 can be solved when we know that y = 3. Using basically algebra, the value of x can be determined, which is -1. Simply subtract 10 from both sides of the equation and then divide both sides by 7.

What is the equation of the line that it is perpendicular to y7x-3 and passes through the origin?
If you mean 7 = 7x-3 then the perpendicular slope is -1/7 and the equation is y = -1/7x
7x -21 Can you please help?

What is the value of x in the equation 7x plus 3 equals 31?
x=4, but this is just very basic algebra, not calculus at all.
What equation of the line that contains the points -3 and 2 and 5 and -5?
Gradient = [2 - (-5)]/[(-3) - 5] = -7/8So equation is y - 2 = -7/8*[x - (-3)]or 8y - 16 = -7x - 21that is 7x + 8y + 5 = 0Gradient = [2 - (-5)]/[(-3) - 5] = -7/8So equation is y - 2 = -7/8*[x - (-3)]or 8y - 16 = -7x - 21that is 7x + 8y + 5 = 0Gradient = [2 - (-5)]/[(-3) - 5] = -7/8So equation is y - 2 = -7/8*[x - (-3)]or 8y - 16 = -7x - 21that is 7x + 8y + 5 = 0Gradient = [2 - (-5)]/[(-3) - 5] = -7/8So equation is y - 2 = -7/8*[x - (-3)]or 8y - 16 = -7x - 21that is 7x + 8y + 5 = 0
What are intercepts for 7x-3y equals 21?
If the equation is 7x - 3y = 21 then (3, 0) and (0, -7).
What is 7x - 4x plus x - 15?
To do this equation, you collect like terms. 7x-4x+x-15 is your original equation, you have 3 terms with "'x'" in them, and they are 7x, -4x, and x. 7x + (-4x) +x simplifies to 4x, because 7-4 = 3 + 1 = 4 (the x is really 1x....). After this, you get 4x-15, which is as simplified as this equation can be.
Why the equation 7x plus 3 equals 7x plus 3?
Why not? The statement is trivially true, meaning it holds for all values of x.
What is the solution to this equation 7x-3(x-6)30?
