Do it by solving the equation; 8 (X-2) = 2 (x + 7)

Do it by solving the equation; 8 (X-2) = 2 (x + 7)

8（x-2）=2（x+7）
8x-16=2x+14
8x-2x=16+14
6x=30
x=5

24 to x = 18 to 15
Write the process and then write the reason

X=20
24 / x = 18 / 15 is reduced to 24 * 15 = 18x
X=360/18
X=20

Solve the equation 1 × 6 of 18 + 1 × 6 of 15 + x = 1 of 15
solve equations:
(1) 1 × 6 of 18 + 1 × 6 of 15 + X of 15 = 1
(2) X of 12 + X of 18 = 2 of 3
(3) 3 x + 4 to x + 5 x = 1
(4) 1 / 24 + 1 / 36 + 1 / x = 1 / 8
(5) 3 / 12 + 5 / 20 + 16 to x = 1
(6) 40% X × 2 + 80% X × 4 = 1
(7) X of 12 + X of 24 = 1

1）x=4
2) X = 24 / 5
3) X = 60 / 47
4）x=18
5)x=8
6)x=10
7)x=8

1 / 3 (x + 46) = 18

1/3（X+46）=18
X+46=3*18
X+46=54
X=54-46
X=8
