Question

1. Solve by trial and error method :
(a) 5x + 3 = 13​

Answer 1

Answer:

5x + 3=13

5x=13-3

5x=10

X=2

Answer 2

Answer:  x=2

Step-by-step explanation:

5x+3=lhs

13=rhs

5x+3=13

let x be 1

5(1)+3=13

8≠13

lhs ≠ rhs

then lets take 2 in place of x

5(2)+3=13

13=13

lhs=rhs

∴ x=2 is the correct answer to the equation
