Question

please solve the following equation.

vii) no
​

Answer 1

Answer:

i. 2x - 1 = - 6 + 5

2x - 1 = - 1

2x = 0

x = 0.

iv. 5y - 7 = 2y + 5

5y - 2y = 5 + 7

3y = 12

y = 4

vii. on cross multiply

3(x - 1) = 5

3x - 3 = 5

3x = 8

x = 8/3

Answer 2

Answer:

(i). (2x-1) -5= -6

-10x+5= -6

-10x = -6-5

-10x= -11

x= -11/-10

x = 1.1

(ii). 5y-7=2y+5

5y-2y= 5+7

3y= 12

y= 12/3

y= 4

(iii). x-1/5 = 1/3

3x-3= 5

3x= 5+3

3x = 8

x= 8/3

x= 2.66666667
