7x+8(x+1/4) = 3(6x-9)-8
7x+8x+2 = 18x - 27 -24
15x + 2 = 18x - 51
+51 + 51
15x + 53 = 18x
-15x = -15x
53 = 3x
17.66 = x
Answer:
A)
Step-by-step explanation:
check that the formula in A works . . .
the 7th term should be 320

= 320
if I know how to do this I this it's y27 oh I know I wrong But it was worth a try right
Step-by-step explanation:
idffffk
7x-5=5x+23
7x-5x=23+5
2x=28
x=28/2
x=14
