$7200.. you would find out what 3.5% of $6000 (210) is and then multiply it by 6 (1200) and then add it to the original $6000
Step 1: 13+5x=30
step 2: subtract 13 from both sides; then youd get 5x=17
step 3: divide by 5
step 4: x=3.4
i hope this is what you were looking for

Answer:
x = 80
Step-by-step explanation:
The whole reason algebra exists is to solve for a variable. Therefore, the only way to get x by itself or to see what x equals is to subtract 20 from both sides. Doing this will make x be all alone on one side of the equation and to see what x is.
x + 20 = 100
x + 20 -20 = 100 -20
x = 80
(8x - 12) + 64 + 68 = 180
(A straight line equals to 180)
8x - 12 + 132 = 180
Combine liked terms
8x + 120 = 180
-120 on both sides
8x = 40
/8 on both sides
x = 5
(8x - 12)
8(5) - 12
40 - 12
28
(2x + 18)
2(5) + 18
10 + 18
28
Answer:
x = 5
