Question

A) 3 (X+62) = 6(X-62)


B) -2(X-62) = -3 (X+62)


C) -5 (X+62) = 10(X+62)


D) -7 (-X-62) = -5 (X-62)


E) -2 (-X+62) = -2 (-X- 62)

Answer 1

A) 3 (X+62) = 6(X-62)

3x + 3.62 = 6x + 6.-62

3x + 186 = 6x - 372

3x - 6x = -372 - 186

-3x = -558

x = -558

-3

x = 186

B) -2(X-62) = -3 (X+62)

-2x -2.-62 = -3x - 3.62

-2x + 124 = -3x - 186

-2x + 3x = -186 - 124

x = -310

C) -5 (X+62) = 10(X+62)

-5x - 5.62 = 10x + 10.62

-5x -310 = 10x + 620

-5x - 10x = 620 + 310

-15x = 930

x = 930

-15

x = -62

D) -7 (-X-62) = -5 (X-62)

7x -7.-62 = -5x - 5.-62

7x + 434 = -5x + 310

7x + 5x = 310 - 434

12x = -124

x = -124

12

x = -10,33

E) -2 (-X+62) = -2 (-X- 62)

2x -2.62 = 2x -2.-62

2x - 124 = 2x + 124

2x - 2x = 124 + 124

0x = 248

x = 248

0

x = 0
