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:
the independant variable is x
Answer:
T₁₀
Step-by-step explanation:
We know the first term is 21, which is a
We work out the difference by taking 21 away from 42 which equals 21.
We then use the general formula:
Tₓ = a + (x-1)(d)
We need to find the term which equals 210
210 = 21 + (x - 1)(21)
210 = 21 - 21 + 21x
210 = 21x
x = 10
Hence it is the 10 term when the thing equals 210.
