Question

5(1-x)+3(1 + x)
1-2x
0.2x + 5 2
3.5x - 35​

Answer 1

Answer:

(i) 5(1-x)+3(1+x)=0

5-5x+3+3x=0

8-2x=0

IF 8 GOES TO RHS SIDE IT TURNS TO NEGATIVE

-2x=-8

x=-8/-2

x= 8/2=4

.•. x= 4

(ii) 1-2x=0

-2x=-1

x=-1/-2

x=1/2

.•. x= 1/2

(iii) 0.2x+5.2=0

0.2x=-5.2

x=-5.2/0.2

x=-26

.•. x= -26

(iv) 3.5x-35=0

3.5x=35

x=35/3.5

x=122.5

.•.x=122.5
