Question

if x=5 what will be 2x + 3x + 13x -7x​

Answer 1

Answer:

2*5+3*5+13*5-7*5

x=5 so,

10+15+65-35

90-35

55

Answer 2

Here we are given an expression 2x + 3x + 13x -7x​

We have to find the value of this expression if x = 5

So, 2x + 3x + 13x -7x​ = 2(5) + 3(5) + 13(5) -7x(5)

                                = 10 + 15 + 65 - 35

                              = 25 + 30

                               = 55

Hence, when x = 5 then the value of  2x + 3x + 13x -7x​ will be 55
