Question

Evaluate the expression 12x-7 for the values of x given in the first column. Value of xValue of expression

Answer 1

The given expression is,

`12x-7\text{ ----(2)}`

Substitute x=1 in the above expression (1) to evaluate the expression for x=1.

`12*1-7=5`

So, when x=1, the value of expression is 5.

Substitute x=2 in the expression (1) (1) to evaluate the expression for x=2.

`12*2-7=24-7=17`

So, when x=2, the value of expression is 17.

Substitute x=3 in the expression (1) (1) to evaluate the expression for x=3.

`12*3-7=36-7=29`

So, when x=3, the value of expression is 29.

Substitute x=5 in the expression (1) to evaluate the expression for x=5.

`12*5-7=60-7=53`

So, when x=5, the value of expression is 53.

Substitute x=8 in the expression (1) to evaluate the expression for x=8.

`12*8-7=96-7=89`

So, when x=8, the value of expression is 89.

Therefore, the table of values is,

1 5

2 17

3 29

5 53

8 89
