Question

a) 9x – 2 = 4x + 18 = 9x – 4x = 18 + 2 = 5x = 20 = x = 20/5= x = 4
b) 5 (2x – 1 ) = 3 (x + 10) = 10x -5 = 3x +30 = 10x – 3x = 30 + 5 = 7x = 35 = x = 35/7 = x =5
c) 7y – 10 = y + 50
d) 4x – 18 + 3x = 10
e) 5x – 91 = 4x – 77
f) 7x + 1 = 5x – 7
g) 4x + 5 = x + 20
h) 2(x + 5 ) – 4 = 26
i) 3(x + 3 ) – 5 = 22
j) 3( x + 2 ) = 2 ( x – 7)
l) 4(2x –1 ) = 3( x+2 )
k) 3(x + 3 ) - 1 = 2
m) 3(2x – 3 ) + x = 5
