10=y*x-1*1.2

Solution for 10=y*x-1*1.2 equation:

Simplifying
10 = y * x + -1 * 1.2

Multiply y * x
10 = xy + -1 * 1.2

Multiply -1 * 1.2
10 = xy + -1.2

Reorder the terms:
10 = -1.2 + xy

Solving
10 = -1.2 + xy

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-1xy' to each side of the equation.
10 + -1xy = -1.2 + xy + -1xy

Combine like terms: xy + -1xy = 0
10 + -1xy = -1.2 + 0
10 + -1xy = -1.2

Add '-10' to each side of the equation.
10 + -10 + -1xy = -1.2 + -10

Combine like terms: 10 + -10 = 0
0 + -1xy = -1.2 + -10
-1xy = -1.2 + -10

Combine like terms: -1.2 + -10 = -11.2
-1xy = -11.2

Divide each side by '-1y'.
x = 11.2y-1

Simplifying
x = 11.2y-1
