in algebra, if what you do to one side of the equation you do to the other side you do not change things and you can solve for the unknown
2n-5 = 7
add 5 to BOTH sides
2n-5 + 5 = 7 + 5
2n = 12
Divide BOTH sides by 2
n = 6
The answer to the problem of 7-3x equals 34 is x equals -9.
m = -1
It is: 7.0*10^0 = 7
this is an additional problem
7 times 18
The answer to the problem of 7-3x equals 34 is x equals -9.

1 x 7 7 x 7
It is: 7.0*10^0 = 7
3(4 plus 7) equals 33
this is an additional problem
7 times 18
2 x 7
210 divided by -7
15 times 7 =105
