5.0625

Step-by-step explanation:

Step 1:

The given expression can be written as

[tex]135X + 120 + 3X + 31 + 4X + 15+ 6X -8 +7X-64 +5X-4 =900[/tex]

On solving the above expression

adding all the X terms and constant terms individually

160X + 90 = 900

Step 2:

160X = 810

X = (810/160)  =5.0625

Answer:

x = 27

Step-by-step explanation:

1. Combine like terms

135 + 120 + 3X + 31 + 4X + 15+ 6X -8 + 7X -64 + 5X -4 = 900

135+120+31+15-8-64-4=225

3+4+6+7+5=25X

2. Replace into the equation

25X + 225 = 900

3. Subtract 225 from both sides of the equal sign

25X = 900 - 225

4. Combine like terms

25X = 675

5. Divide each side of the equal sign by 25 to get X by itself

X = 27
