-7x + 5 = -9 -7x = -14 7x = 14 x = 2

3/7x + 5 = 87x(3/7x + 5) = 8(7x)3(7x/7x) + (7x)(5) = 8(7x)3 + 35x = 56x3 + 35x - 35x = 56x - 35x3 = 21x3/21 = 21x/211/7 = x

23 = 7x + 7x - 5 = 14x - 5 14x = 23 + 5 = 28 x = 28/14 = 2

-8 + 7(6x) + 3 = -7x - 5 - 1-8 + 42x + 3 = -7x - 5 - 142x - 8 + 3 = -7x - 5 + (-1)42x - 5 = - 7x - 642x + 7x - 5 + 5 = - 7x + 7x - 6 + 549x = -149x/49 = -1/49x = -1/49

7x - 9 = 3x + 5 7x - 3x - 9 = 5 7x - 3x = 5 + 9 4x = 14 x = 14/4

7x+5-14 = 28 7x = 28+14-5 7x = 37 x = 37/7 = 5.'285714' recurring

-9-7x=-5 express first the equation in terms of x, where, 7x=-9+5 then, 7x=-4 thus, x=-4/7

X = 10 7x-5=65 +5 +5 7x=70 /7 /7 So X=10

7x+20-15=7x+5

Let x be the varible: 7x-5 = 37 7x = 37+5 7x = 42 x = 6
