Question

in algebra 1 the question is--Evaluate the expression when x=5
4⋅x−3...please help me :)

Answer 1

We have been given that

x = 5

So,
4x - 3
=4(5) - 3      (Substituting x with 5)
=20 - 3
=17

Answer 2

X=5
we must put 5 in the place of X
so, 4X-3(4X means multiplication) will be 4x5-3 
4x5-3 = 20-3=17
