Simplifying
12x * 42 + -12 + -32 = 1972
Reorder the terms for easier multiplication:
12 * 42x + -12 + -32 = 1972
Multiply 12 * 42
504x + -12 + -32 = 1972
Reorder the terms:
-12 + -32 + 504x = 1972
Combine like terms: -12 + -32 = -44
-44 + 504x = 1972
Solving
-44 + 504x = 1972
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '44' to each side of the equation.
-44 + 44 + 504x = 1972 + 44
Combine like terms: -44 + 44 = 0
0 + 504x = 1972 + 44
504x = 1972 + 44
Combine like terms: 1972 + 44 = 2016
504x = 2016
Divide each side by '504'.
x = 4
Simplifying
x = 4
Hope this helps
