Question

4 + 2x + 1x - 4 = 30

How can I solve this and please explain step by step!

Answer 1

X=10
1.add the numbers that have the same value etc. So, 2x+1x=3x
2. You can subtract 4 from 4 to get zero
3. It’s now basically 0+3x=30
30is divisible by 3 so x is now 10

Answer 2

x = 10

Explanation:

To find the value of x:

1) add up like-terms

4 + 2x+1x-4=30

4 + 3x - 4 = 30

2) Add up the number on the left side

0 + 3x = 30

3x = 30

3) isolate the x

3x/3 = 30/3

x = 10
