Answer 1

a) m -3/2 = -9/4

m = -3/4 = -0.75

b) y + 5.4 = - 0.7

y = −6.1

c) 1.5x = x - 2

x = -4

d) 88+ x/11 = 3

x = −935

​​  

e) - 5w + 8 ( 1 + 7 w) = -8

w = -16/51

f) 5 (4y + 2) = 2 (8 + 6y)

y = 3/4

g) 5 ( 2m + 6 ) = 4 ( 5 + 2m ) + 3m

m = 10

h) 3 + 5a = 8 - 40a + 6

a = 11/45

i) 2 ( x + 2) = x - 2

x = -6

j) 4 ( z + 2) = 3 ( z + 1)

z = -5

k) x + 4x - 2 + x = 28

x = 5

l) x/4 - 3 = x/ 8 + 1

x = 32

m) 2x - 5 / 4 = 5

​x = 25/8
