Ellen picks a number. She adds 3 to it and then multiplies the result by 2. She then subtracts 7 from this result. Her final result is 53. If x is the number she originally selected, pick the algebraic equation that represents these operations.

53 = 2(x + 3) - 7/
53 = 2x + 3 - 7 /
7 = 2(x + 3) + 53 /
53 = 3(x + 2) - 7/

Question

Ellen picks a number. She adds 3 to it and then multiplies the result by 2. She then subtracts 7 from this result. Her final result is 53. If x is the number she originally selected, pick the algebraic equation that represents these operations.


53 = 2(x + 3) - 7/
 53 = 2x + 3 - 7 /
 7 = 2(x + 3) + 53 /
 53 = 3(x + 2) - 7/

anonymous · Answer

Starts with x, then add 3: x+3
Muliply that by 2: 2(x+3)
Subtract 7: 2(x+3)-7
Set it equal to 53...
