Question

the value of x +7 +4 (x-5) for x =​

Answer 1

Step-by-step explanation:

Expression x+7+4(x-5)=5x-13x+7+4(x−5)=5x−13

The value of x+7+4(x-5)=-3x+7+4(x−5)=−3 at x=2.

Step-by-step explanation:

Given : Expression x+7+4(x-5)x+7+4(x−5)

To find : Simplify the expression and find the value ?

Solution :

Step 1 - Write the expression,

x+7+4(x-5)x+7+4(x−5)

Step 2 - Solve the bracket,

=x+7+4x-20=x+7+4x−20

Step 3 - Solve the like terms,

=5x-13=5x−13

So, x+7+4(x-5)=5x-13x+7+4(x−5)=5x−13

Substitute x=2 in the expression,

5(2)-13=10-13=-35(2)−13=10−13=−3

The value of x+7+4(x-5)=-3x+7+4(x−5)=−3 at x=2.
