Let f(x)=x+1, and g(x)= 5x-1. Find all x for which f(x)=g(x)
Hey Nenamm,
As given, F(X) = G(X)
So,
--> x+1 = 5x-1
--> 2 = 4x
--> x = 1/2
Hope I helped. (: xx
f(x) = g(x)
<=>x + 1 = 5x - 1
<=> 5x - x = 1 + 1
<=> 4x = 2
<=> x = 1/2
x+1=5x-1
2=4x
.5 = x
We need to find all x such that
i.e. x + 1 = 5x - 1
=> 5x - x = 1 + 1
=> 4x = 2
=> x = 1/2
x+1 = 5x - 1
1+1 = 4x
2 = 4x
2/4 = x
x = 1/2 -> 0.5
X is any number a/b where a/b = 0.5
subtract x from both sides
1=4x-1
add 1 to both sides
divide both sides by 4
1/2=x
