Question

2. Solve.
a) 5x - (3x - 1) = x - 4​

Answer 1

Answer:

Simplifying

5x + -1(3x + -1) = x + -4

Reorder the terms:

5x + -1(-1 + 3x) = x + -4

5x + (-1 * -1 + 3x * -1) = x + -4

5x + (1 + -3x) = x + -4

Reorder the terms:

1 + 5x + -3x = x + -4

Combine like terms: 5x + -3x = 2x

1 + 2x = x + -4

Reorder the terms:

1 + 2x = -4 + x

Solving

1 + 2x = -4 + x

Solving for variable 'x'.

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

Add '-1x' to each side of the equation.

1 + 2x + -1x = -4 + x + -1x

Combine like terms: 2x + -1x = 1x

1 + 1x = -4 + x + -1x

Combine like terms: x + -1x = 0

1 + 1x = -4 + 0

1 + 1x = -4

Add '-1' to each side of the equation.

1 + -1 + 1x = -4 + -1

Combine like terms: 1 + -1 = 0

0 + 1x = -4 + -1

1x = -4 + -1

Combine like terms: -4 + -1 = -5

1x = -5

Divide each side by '1'.

x = -5

Simplifying

x = -5
