Question

What is the solution set for 4x−3=2x+5 , given the replacement set {2, 3, 4, 5} ?

x = 2
x = 3
x = 4
x = 5

Answer 1

X = 2
i think so
4 - 2 = 2

Answer 2

We have the equation:

4x - 3 = 2x + 5

Let's to change "-3" to the right side of equation, but changing the sinal

4x = 2x + 5 + 3

4x = 2x + 8

Now, we let's to change "2x" to the left side of equation. But, we also will go to change the sinal

4x - 2x = 8

2x = 8

We pass "2" dividing by the 8

x = 8 ÷ 2

x = 4

Tha answer to this questions is ,

X = 4

I hope this has helped.
