Answer 1

$\huge \bold \purple{solution}$

Solve 1.) (@). 4x - 5y = 0

It is an equation.

(b). 7x = 9x - 12

It is an equation.

(c). (3x + y) - 2y

It is an expression.

(d). 7x - 3

It is an expression.

(e) 6x - 9 = 28

It is an equation.

Solve 2.) Put x= 7 in equation x + 5 = 2

=>. 7 + 5 = 2

=>. 12 ≠ 2

No, x = 7 is not the solution of x + 5 = 2.

Solve 3.) Put x = 3 in equation x - 2 = 1

=>. 3 - 2 = 1

=>. 1 = 1

Yes, x = 1 is the solution of x - 2 = 1

Solve 4.) Put x = 3 in x + 2 = 5

=>. 3 + 2 = 5

=>. 5 = 5

Yes, x = 3 is the solution of x + 2 = 5

Solve 5.) (@). x + 3 = 7;(2, 3, 4, 5)

First, put x = 2

=>. 2 + 3 = 7

=>. 5 ≠ 7

No, x = 2 Is not the solution of x + 3 = 7

Put x = 3

=>. 3 + 3 = 7

=>. 6 ≠ 7

No, x = 3 Is not the solution of X + 3 = 7

Put X = 4

=>. 4 + 3 = 7

=>. 7 = 7

Yes, X= 4 is the solution of X + 3 = 7

(b). x - 5 = 3 (4, 5, 7, 8)

First, put x = 4

=>. 4 - 5 = 3

=>. (-1) ≠ 3

No, x = 4 Is not the solution of X - 5 = 3

Put X = 5

=>. 5 - 5 = 3

=>. 0 ≠ 3

No, X = 5 is not the solution of X - 5 = 3

Put X = 7

=>. 7 - 5 = 3

=>. 2 ≠ 3

No, X = 7 is not the solution of x - 5 = 3

Put X = 8

=>. 8 - 5 = 3

=>. 3 = 3

Yes, X = 8 is the solution of X - 5 = 3

Hope it's help you!
