which of these would be a helpful first step in solving the equation? check all that apply. 7x - 9 = 2x + 21
Answers
Answer: E. Subtract 2x
Step-by-step explanation:
Subtracting 2x would remove a bit from both equations, giving us 5x - 9 = 12. This would make it easier now that we only have one number on a side.
Hope this helps!

-2(x+7)= x-34+2x i need the steps
Answers
♡ The Question ♡
・-2 (x + 7) = x -34 + 2x
*୨୧ ┈┈┈┈┈┈┈┈┈┈┈┈ ୨୧*
* ♡ The Answer ♡
・x = 4
*୨୧ ┈┈┈┈┈┈┈┈┈┈┈┈ ୨୧*
♡ The Explanation/Step-By-Step ♡
・-2 (x + 7) = x -34 + 2x
-2 (x + 7) = x + 2x - 34
-2 (x + 7) = 3x - 34
-2 (x + 7) : -2x - 14
-2 (x + 7)
Apply the distributive law! : a(b + c) = ab + ac
a = -2, b = x, c = 7
= -2 + (-2) x 7
Apply minus (-) plus rules!
+ (-a) = -a
= -2x - 2 x 7
Multiply the numbers! : 2 x 7 = 14
= -2x - 14
-2x - 14 = 3x - 34
Add 14 to both sides!
-2x - 14 + 14 = 3x - 34 + 14
Simplify!
-2x = 3x - 20
Subtract 3x from both sides!
-2x - 3x = 3x - 30 - 3x
Simplify!
-5x = -20
Divide both sides by -5!
-5x/-5 = -20/-5
Simplify! : -5x/-5 : x
Apply the fraction rule! : -a/-b = a/b
= 5x/5
Divide the numbers! : 5/5 = 1
= x
Simplify! : -20/-5 : 4
-20/-5
Apply the fraction rule! : -a/-b = a/b
= 20/5
Divide the numbers! 20/5 = 4
= 4
x = 4

Larry invests $100 in a savings plan. The plan pays 5 1/2% interest each year on
his $100 account balance. The following chart shows the balance on his account
after each year for the next 5 years. He did not make any deposits or
withdrawals during this time.
Answers
Answer:
100*1.055^5 = $130.70
Step-by-step explanation:
the simple way to work this out is to think about how much the savings increase by each year.
Balance * (1+interest)^years
So convert the interest rate to decimals and add it to one. This is the amount the balance is multiplied by each year. Raise it to the power of the years of interest and you get the result.
For 5 years it is
100*1.055^5 = $130.70
