1/7+2x/3=(15x-3)/21 make all terms have a common denominator of 21
3+14x=15x-3 subtract 3 from both sides
14x=15x-6 subtract 15x from both sides
-x=-6 divide both sides by -1
x=6
*Notice the use of parentheses in this format to make it clear what the numerators and denominators are...

Step-by-step explanation:
To find a percentage of a number, you multiply the number by the decimal form of the percentage. The decimal form of 30% is 0.3, so we multiply 26 by 0.3:
26 x 0.3 = 7.8
30% of 26 is 7.8
Answer:
y = 1000 x .30 (+ 1000)
Step-by-step explanation:
since it grows by 30%, you multiply .30 (the decimal version of 30%) and 1000 (your initial amount) to find how much it grows. Then you add $1000 at the very end, because that is how much you started with.
