Tolong di jawab secepatnya ya

a. m - 9 = 13
m = 13 + 9
m = 22

b. -11 + x = 3
x = 3 + 11
x = 14

c. 2a + 1 = a - 3
2a - a = -1 - 3
a = -4

d. 12 + 3a = 5 + 2a
3a - 2a = -12 + 5
a = -7

e. 3(x + 1) = 2(x + 4)
3x - 3 = 2x + 8
3x - 2x = 3 + 8
x = 11

f. 5(y - 1) = 4y
5y - 5 = 4y
5y - 4y = 5
y = 5

g. 4(3 - 2y) = 15 - 7y
12 - 8y = 15 - 7y
12 - 15 = 8y - 7y
-3 = y

h. 3(2y - 3) = 5(y - 2)
6y - 6 = 5y - 10
6y - 5y = 6 - 10
y = -4

i. 8 - 2(3 - 4y) = 7y - 1
8 - 6 + 8y = 7y - 1
2 + 8y - 7y = -1
y = -2 - 1
y = -3

j. 5x + 7(3x + 2) = 6(4x + 1)
5x + 21x + 14 = 24x + 1
26x - 24x = -14 + 1
2x = -13
x = -13 : 2
x = -6,5

semoga membantu yaa
