What is x + 8 = 15 + 4x - 7​

x=0

Step-by-step explanation:

x = 0

Explain:

Step 1:

x + 8 = 15 + 4 − 7

x + 8 = 8 + 4

Step 2:

x + 8 = 8 + 4

x + 8 = 4 + 8

Step 3:

x + 8 = 4 + 8

x + 8 − 8 = 4 + 8 − 8

Step 4:

x = 4x

x − 4x = 4x − 4x

Step 5:

x = 0/ -3

So therefore, x = 0

x=24

Step-by-step explanation:

0.22(x+6)=0.2x+1.8

simplify the given equation

0.22x+1.32=0.2x+1.8

shift same kind of variables on one side

0.22x-0.2x=1.8-1.32

0.02x=0.48

For x

x=0.48/0.02

x=24

Check:

For checking subsitute the calculated value x if both sides of x are equal  then its true...

0.22(24+6)=0.2(24)+1.8

5.28+1.32=4.8+1.8

6.6=6.6
