Question

1) x – 3 = 3 – x 2) 2x + 2 – 3x + 5 = 3 + 2 3) 3x – 2 – 3 (- 1 + 2x) = 2 – 2(x - 1)

Answer 1

Respuesta:

Explicación paso a paso:

1)

$x-3=3-x\\\\x-3+3=3-x+3\\\\x=-x+6\\\\x+x=-x+6+x\\\\2x=6\\\\\frac{2x}{2}=\frac{6}{2}\\\\x=3$

2)

$2x+2-3x+5=3+2\\\\2x+2-3x+5-2=3+2-2\\\\2x-3x+5=3\\\\-x+5=3\\\\-x+5-5=3-5\\\\-x=-2\\\\\frac{-x}{-1}=\frac{-2}{-1}\\\\x=2$

3)

$3x-2-3\left(-1+2x\right)=2-2\left(x-1\right)\\\\-3x+1=-2x+4\\\\-3x+1-1=-2x+4-1\\\\-3x=-2x+3\\\\-3x+2x=-2x+3+2x\\\\-x=3\\\\\frac{-x}{-1}=\frac{3}{-1}\\\\x=-3$

Answer 2

Respuesta:

1) x= 3

2) x=2

3) x = 1

Explicación paso a paso:

1) x - 3 = 3 - x

2x = 6

x = 3

2) 2x + 2 - 3x +5 = 3 + 2

2 - x = 0

x = 2

3) 3x - 2 - 3 (-1 + 2x) = 2 - 2 (x - 1)

3x - 2 + 3 - 6x = 2 - 2x +2

5x = 5

x = 1
