Question

Помогите пж,.........​

Answer 1

#1
10y = 200
Y = 20

#2
-15a - 5 - 11 = 16
-15a = 32
A = - 32/15 =

#3
12 - 2x - 6 = 26
2x = -20
X = -10

#4
12x - 24 = 3x - 6
9x = 18
X = 2

#5
X = 16

#6
3x = -3
X = -1

Answer 2

$3 + 11y = 203 + y\\11 y - y = 203 - 3\\10y = 200\\y = 200 : 10\\y = 20$

$-5(3a + 1) - 11 = 16\\-15a - 5 - 11 = 16\\-15a = 16 + 5 + 11\\-15a = 32\\a = -2\frac{2}{15}$

$12 - 2(x + 3) = 26\\12 - 2x - 6 = 26\\-2x = 26 - 12 + 6\\-2x = 20\\x = -10$

$3(4x - 8) = 3x - 6\\12x - 24 = 3x - 6\\12x - 3x = -6 + 24\\9x = 18\\x = 2$

$6x - 12 = 5x + 4\\6x - 5x = 4 + 12\\x = 16$

$5x + 3 = 2x\\5x - 2x = -3\\3x = -3\\x = -1$
