Question

please solve this equation and check the answer 2x+1=x+22 , 5x-8= -2x+6 , 2x/7=6
if you solve this equations I will mark the brainliest ​

Answer 1

Answer:

2x+1=x+22, x=19

5x-8= -2x+6, x=2

2x/7=6, x=21

Answer 2

(i) 2x + 1 = x + 22

2x - x = 22 - 1
x = 21

To check, substitute the value of x in the equation..

2(21) + 1 = 21 + 22
43 = 43
LHS = RHS

(ii) 5x - 8 = -2x + 6

5x + 2x = 6 + 8
7x = 14
x = 14/7
x = 2

To check, substitute the value of x in the equation..

5(2) - 8 = - 2(2) + 6
10 - 8 = - 4 + 6
2 = 2
LHS = RHS

(iii) 2x/7 = 6

2x = 6x7
2x = 42
x = 42/2
x = 21

To check, substitute the value of x in the equation..

2(21)/7 = 6
42/7 = 6
6 = 6
LHS = RHS
