Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '4.2x' to each side of the equation.
1.8 + -3.7x + 4.2x = 0.3 + -4.2x + 4.2x
Combine like terms: -3.7x + 4.2x = 0.5x
1.8 + 0.5x = 0.3 + -4.2x + 4.2x
Combine like terms: -4.2x + 4.2x = 0.0
1.8 + 0.5x = 0.3 + 0.0
1.8 + 0.5x = 0.3
Add '-1.8' to each side of the equation.
1.8 + -1.8 + 0.5x = 0.3 + -1.8
Combine like terms: 1.8 + -1.8 = 0.0
0.0 + 0.5x = 0.3 + -1.8
0.5x = 0.3 + -1.8
Combine like terms: 0.3 + -1.8 = -1.5
0.5x = -1.5
Divide each side by '0.5'.
x = -3
Simplifying
x = -3
