A) 24m = 12 1/24 x 24m = 1/24 x 12 m = 12/24 = 1/2 b) 3z +11 =- 28 3z + 11 - 11 = -28 - 11 3z = -39 z =-39/3 = -13 c) 25-4y = 6y + 15 25 -4y+ 4y = 6y + 4y + 15 25 = 10y + 15 25-15 = 10y 10 = 10y y = 10/10 = 1 d) -4x -15 = 1-8x -4x + 8x -15 = 1 -8x + 8x 4x - 15 = 1 4x-15+15 = 1 + 15 4x = 16 x = 16/4 = 4 e) 6/a + 2 = 4 6/a + 2 -2 = 4 -2 6/a = 2 6/a x a = 2 x a 6 = 2a a = 6/2 a = 3
1/24 x 24m = 1/24 x 12
m = 12/24 = 1/2
b) 3z +11 =- 28
3z + 11 - 11 = -28 - 11
3z = -39
z =-39/3 = -13
c) 25-4y = 6y + 15
25 -4y+ 4y = 6y + 4y + 15
25 = 10y + 15
25-15 = 10y
10 = 10y
y = 10/10 = 1
d) -4x -15 = 1-8x
-4x + 8x -15 = 1 -8x + 8x
4x - 15 = 1
4x-15+15 = 1 + 15
4x = 16
x = 16/4 = 4
e) 6/a + 2 = 4
6/a + 2 -2 = 4 -2
6/a = 2
6/a x a = 2 x a
6 = 2a
a = 6/2
a = 3
m= 12-24
m= -12
b. 3z+11 = 28
3z= 28-11
3z= 17
z= 17/3
z= 5 2/3
c.25-4y =6y + 15
-4y+-6y = 15-25
-10y = -10
y= -10/-10
y= 1
d. -9x -15 = 1-8x
-9x+8x= 1 + 15
-x = 16
x = 16/-1
x= -16
