Ok "translating to an algebra statement means make all the words numbers and the operations symbols. Okay so what does it say you need to read it: Then decide what will represent the number that is unknown. How about r. 6 X (15 + r) = 2r-7

6 (15+X) = 2X-7
OR
6 (15+X) = 2 (X-7)
It depends on the meaning of "twice the same number decreased by seven"
Is it twice the number THEN decreased by seven (formular 1)
or is it two times the number AFTER it is decreased by seven (formula 2)
I hope this helps.

6 * (a+15) = 2 * (a-7) â 6a + 90 = 2a -14 â 4a = -104 â
"a = -26"
Just for test:
6 * [(-26)+15] = 6 * (-11) = -66
2 * [(-26) - 7] = 2 * (-33) = -66
The results are the same. So, the answer is correct. "a = -26"
