Question

a) 6x = 2x + 16 (R:4)

b) 2x - 5 = x + 1

2X -X= +1 +5

X =+5

c) 2x + 3 = x +4

d) 5x + 7 = 4x + 10

e) 4x - 10 = 2x + 2

f) 4x - 7 = 8x-2

4X-8X = -2 +7

-4X = + 5

X= +5/-4 X= - 5/4

g) 2x + 1 = 4x - 7

h) 9x + 9 + 3x = 15

9X +3X= 15-9

12X = 6 X= 6 /12 = 1/2

i) 16x - 1 = 12x + 3

y) 3x - 2 = 4x + 9

I) 5x -3 + x = 2x + 9​
