Answer 2

Simplifying

(0.75x + 6) + -1(2.5x + -1.9) = 0

Reorder the terms:

(6 + 0.75x) + -1(2.5x + -1.9) = 0

Remove parenthesis around (6 + 0.75x)

6 + 0.75x + -1(2.5x + -1.9) = 0

Reorder the terms:

6 + 0.75x + -1(-1.9 + 2.5x) = 0

6 + 0.75x + (-1.9 * -1 + 2.5x * -1) = 0

6 + 0.75x + (1.9 + -2.5x) = 0

Reorder the terms:

6 + 1.9 + 0.75x + -2.5x = 0

Combine like terms: 6 + 1.9 = 7.9

7.9 + 0.75x + -2.5x = 0

Combine like terms: 0.75x + -2.5x = -1.75x

7.9 + -1.75x = 0

Solving

7.9 + -1.75x = 0

Solving for variable 'x'.

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

Add '-7.9' to each side of the equation.

7.9 + -7.9 + -1.75x = 0 + -7.9

Combine like terms: 7.9 + -7.9 = 0.0

0.0 + -1.75x = 0 + -7.9

-1.75x = 0 + -7.9

Combine like terms: 0 + -7.9 = -7.9

-1.75x = -7.9

Divide each side by '-1.75'.

x = 4.514285714

Simplifying

x = 4.514285714
