Question

Solve +4x + 1 = 0
Solve 2 + 5x - 4 = 0
Solve 3 - x - 5 = 0

Answer 1

4x+1=0

4x=0-1

4x=-1

X=-1/4

2+5x-4=0

2+5x=0+4

2+5x=4

5x=4-2

5x=2

X=2/5

3-x-5=0

3-x=0+5

3-x=5

X=5+3

X=8

hope it helps you make a brainliest and say thanks

Answer 2

$\huge{\underline{\tt{QUESTION:-}}}$

Solve the following :-

(i) 4x + 1 = 0

(ii) 2 + 5x - 4 = 0

(iii) 3 - x - 5 = 0

$\huge{\underline{\tt{ANSWER:-}}}$

(i) 4x + 1 = 0

sol. => 4x = 0 - 1

4x = -1

x = -1/4

(ii) 2 + 5x - 4 = 0

sol. => 5x - 4 = 0 - 2

5x - 4 = -2

5x = -2 + 4

5x = 2

x = 2/5

(iii) 3 - x - 5 = 0

sol. => 3 - x = 0 + 5

3 - x = 5

-x = 5 - 3

- x = 2

x = -2
