Question

Evaluate : 5-3(x-1) when x=7

Answer 1

Answer:

$\boxed{ \bold{ \boxed{ \sf{ - 13}}}}$

Step-by-step explanation:

Given , x = 7

let's find :

$\sf{5 - 3(x - 1)}$

Plug the value of x

⇒$\sf{5 - 3(7 - 1)}$

Subtract 1 from 7

⇒$\sf{5 - 3 \times 6}$

Multiply the numbers

⇒$\sf{5 - 18}$

Calculate

⇒$\sf{ - 13}$

Answer 2

The value of 5-3(x-1) when x=7 is -13.

What is Evaluate meaning?

Evaluation is nothing but to solve an algebraic expression means to find the value of an expression by replacing the value of the variable in it.

To evaluate the expression value, we simply substitute the variable from its given value and simplify the expression by using order of operations.  

In our case, the given expression is:

5-3(x-1)

Substitute the given number i.e., 7 for the variable in the expression:

5-3(7-1)

Solve the bracket first:

5-3(6)

Now solve the multiplication part:

5 - 18

Finally Subtract 5 from -18, we get:

-13

Hence the final value of the expression is -13 at x=7.
