Step 1
Let the number be a,
Three times a number increased by 8 3 a + 8
Is no more than' means it can be the same as or less than the number decreased by 4 :
3 a + 8 a - 4
Step 2
Take the terms with variable a to left hand side and keep the other terms on right hand side. Apply transposition rules:
3 a - a - 8 - 4
2 a - 12
a - 6
