X=4.2666666666667
Double first equation: 10x + 2y = 10Subtract second equation: 7x = 7x = 1, y = 0
7x = -3y + 12
It is an equation and the value of x is 8
Why not? The statement is trivially true, meaning it holds for all values of x.
56x^2 + 96x + 40
-2x + 8 = 7x - 10 is technically an equation, in and of itself.
X=4.2666666666667
7x + y = 8 Subtract 7x from each side of the equation: y = -7x + 8
Double first equation: 10x + 2y = 10Subtract second equation: 7x = 7x = 1, y = 0
7x = -3y + 12
It is an equation and the value of x is 8
Why not? The statement is trivially true, meaning it holds for all values of x.
7x + 9 = 51 7x = 42 x = 42/7 = 6
Im guessing that the equation is 7x - 2y +3z= 19 so the answer is 7x + 3z= 19
It is an equation and the value of x is 2
It is an equation and the value of x is 12
