Oh, dude, the value of x in that equation is 5. Like, you just add 3 to both sides, then divide by 7. It's like basic math, man.
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.
If you mean: y=7x -3 then it is a proportional relationship of a straight line equation.
If you mean x = 3 then the value of 7x-2x is 21-6 = 15
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
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
32= -3 - 7x 32 + 3 = - 7x 35= - 7x 35/7 = -x 5 = -x -5= x
The equation (7x + 37x + 3 = 0) simplifies to (44x + 3 = 0), which has a single solution for (x). However, if the equation were presented in a different form, such as (7x + 37x + 3 = 7x + 37x + 3), it represents an identity that holds true for all values of (x), thus having infinitely many solutions. This occurs when both sides of the equation are equivalent regardless of the value of (x).
It is an equation and the value of x is 2
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.

If you mean 7 = 7x-3 then the perpendicular slope is -1/7 and the equation is y = -1/7x

x=4, but this is just very basic algebra, not calculus at all.
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
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.
If the equation is 7x - 3y = 21 then (3, 0) and (0, -7).
Why not? The statement is trivially true, meaning it holds for all values of x.
