Answer 1

Answer:

B. 7p + 2 = 37

Step-by-step explanation:

given,

14p+4=74

14p=70

p=5

substitute in the given options

7p+2=37

7(5)+2

37

hence proved

Answer 2

Given

Equation- 14p + 4 = 74

To Find

the equivalent equation

Explanation:

14p+4=74

14p=70 -4

14p = 70

p=5

On substituting the value of p in the (b) option we get

7p+2=37

7×5 = 37-2

7×5 = 35

35 = 35

Hence proved option (b)  7p+2=37 is the equivalent equation.
