Simplifying
4x + - 8 = - 4(2x + - 3) + 4
Reorder the terms : - 8 + 4x = - 4(2x + - 3) + 4
Reorder the terms : - 8 + 4x = - 4( - 3 + 2x) + 4 - 8 + 4x = ( - 3 * - 4 + 2x * - 4) + 4 - 8 + 4x = (12 + - 8x) + 4
Reorder the terms : - 8 + 4x = 12 + 4 + - 8x
Combine like terms : 12 + 4 = 16 - 8 + 4x = 16 + - 8x
Solving - 8 + 4x = 16 + - 8x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '8x' to each side of the equation.
- 8 + 4x + 8x = 16 + - 8x + 8x
Combine like terms : 4x + 8x = 12x - 8 + 12x = 16 + - 8x + 8x
Combine like terms : - 8x + 8x = 0 - 8 + 12x = 16 + 0 - 8 + 12x = 16
Add '8' to each side of the equation.
- 8 + 8 + 12x = 16 + 8
Combine like terms : - 8 + 8 = 0
0 + 12x = 16 + 8
12x = 16 + 8
Combine like terms : 16 + 8 = 24
12x = 24
Divide each side by '12'.
X = 2
Simplifying
x = 2.
800, 410 = Ochociento mil, cuatrociento diez. 700, 009 = setecientos mil nueve. 2, 100, 080 = dos millones cien mil ochenta.
Espero haberte ayudado, la solución está en la parte de arriba ♡!
Explicación paso a paso : m∠a + m∠b = 180 18x + 4 + 4x = 180 22x = 180 - 4 22x = 176 x = 176 / 22 x = 8.
