Question

Solve the following equations with explanation :

a) 2x/3+5/2=4
b) 34-5(p+1)=4​

Answer 1

Answer:

Step-by-step explanation:

a. 2x / 3 + 5 / 2 = 4

= > 2x / 3 + 5 / 2 = 4

= > 2x / 3 = 4 - 5 / 2

= > 2x / 3 = ( 8 - 5 ) / 2

= > 2x / 3 = 3 / 2

= > 4x = 9

= > x = 9 / 4

Hence the required numeric value of x is 9 / 4.

b. 34 - 5( p + 1 ) = 4

= > 34 - 5( p + 1 ) = 4

= > 34 - 4 = 5( p + 1 )

= > 30 = 5( p + 1 )

= > 30 / 5 = p + 1

= > 6 = p + 1

= > 6 - 1 = p

= > 5 = p

Hence the required numeric value of p is 5.

Answer 2

Answer: A. x=9/4 B. p=5

Step-by-step explanation:

A. 2x/3+5/2=4

2x/3=4-5/2

2x/3=8-5/2

2x/3=3/2

x=3/2×3/2

x=9/4

B.34-5(p+1)=4

34-5p-5=4

29-4=5p

25=5p

25/5=p

5=p
