Three less than triple a number is the same as the number plus 57. What is the number?
1 answer:
Make this into an equation keeping the number as x
3x-3 = 57+x
3x-x = 57+3
2x=60
x= 30
prove this by substituting the x
30*3 -3 =57+30
87=87
there you have it :)

Answer:
x = 5 z = 94
Step-by-step explanation:
12x + 26 = 86
12x = 60
x = 5
360 - 172 = 188
z = 188 : 2 = 94
