no.. x equals 11

x = 40

y = -2.5 is a equation. And solution to the equation is finding the value of the variable. If we see the equation y is already equal to -2.5 which is the solution to the equation.
6.375
a = 16
-20
18x1, 9x2, 6x3, 12x1.5, etc
9x+6=51 9x = 45 x= 5 9x-6=51 9x = 57 x= 6.33
7x + 9 = 51 7x = 42 x = 42/7 = 6
6x3 - x2 + 17 = 2x2 + 47 6x3 - x2 - 2x2 = 47 - 17 x2(6x - 1 - 2) = 30 this is the simplest factorisation.
6x3=18
51
The answer is 18. - n/3=6 - n=6x3 - n=18
51% = 51/100
7x = 2 = 51 is not a valid equality. 2 cannot be equal to 51.
