Q - 12 = 89 Add 12 to both sides of the equation. Q - 12 + 12 = 89 + 12 Q = 101
7q+13 = 52 7q = 52-13 7q = 39 q = 39/7
In algebra, "twice q" refers to the expression that represents two times the variable ( q ). Mathematically, it is written as ( 2q ). This indicates that whatever value ( q ) takes, it should be multiplied by 2. For example, if ( q = 3 ), then "twice q" would equal ( 6 ).
If the number is 'Q' then the expression is: [ 0.26 Q ]
