Question

1) 4x-3=2x+7
2) 9x-1=4x+64
3) 8x-1=6x+5
4) 11x+1=2x+181
5) 15x-13=-5x+387
6) 25x+8=-9x+42

Answer 1

$1)4x - 3 = 2x + 7 \\ 4x - 2x = 7 + 3 \\ 2x = 10 \\ x = 5$

$2)9x - 1 = 4x + 64 \\ 9x - 4x = 64 + 1 \\ 5x = 65 \\ x = 13$

$3)8x - 1 = 6x + 5 \\ 8x - 6x = 5 + 1 \\ 2x = 6 \\ x = 3$

$4)11x + 1 = 2x + 181 \\ 11x - 2x = 181 - 1 \\ 9x = 180 \\ x = 20$

$5)15x - 13 = - 5x + 387 \\ 15x + 5x = 387 + 13 \\ 20x = 400 \\ x = 20$

$6)25x + 8 = - 9x + 42 \\ 25x + 9x = 42 - 8 \\ 34x = 34 \\ x = 1$

Answer 2

Explicación paso a paso:

1)

4x-3=2x+7

4x-2x=7+3

2x=10

X=10/2

X=5

2)

9x-1=4x+64

9x-4x=64+1

5x=65

X=65/5

X=13

3)

8x-1=6x+5

8x-6x=5+1

2x=6

X=6/2

X=3

4)

11x+1=2x+181

11x - 2x =181-1

9x=180

X=180/9

X=20

5)

15x-13=-5x+387

15x+5x=387+13

20x=400

X=400/20

X=20

6)

25x+8=-9x+42

25x + 9x=42-8

34x=34

X=34/34

X=1
