The Equation 7-x=12 can be solved as follows. First the X should be made positive (which can be done my moving it to the other side of the Equal Sign. 7=12+x. Then, the X must be made to be by itself, by moving the 12 to other side of the equation this can be accomplished. 7-12=x (remember that when you move a value across the Equal Sign it changes from positive to negative and negative to positive). After this you solve 7-12=X (7-12= -5) X= -5
7x = 3x - 12 4x=-12 x=-3
You cannot solve one linear equation with two unknown variables.
The math equation of X times 2 - 7x + 12 times 0 equals 2X - 7x.
7x = -3y + 12
It is a linear equation in a single variable, x.
7x=42 x=42/7 or, x=6
Using the quadratic equation formula: x = 8.42 or x = -1.42
7x = 3x - 12 4x=-12 x=-3
You cannot solve one linear equation with two unknown variables.
7x + y = 8 Subtract 7x from each side of the equation: y = -7x + 8
The math equation of X times 2 - 7x + 12 times 0 equals 2X - 7x.
7x = -3y + 12
The required equation is: -7x = 63
It is an equation and the value of x is 12
It is a linear equation in a single variable, x.
7x = 12Divide each side by 7:x = 12/7 = 1.71 (rounded)
x=2 because 9-(14)=-5
