to solve 18-70 you would subtract just like any other equation. 18-70 is equal to a negative number, -52.
5/6-7/18
3X+70-7*18=0 3X+70-126=0 3X-56=0 3X=56 x=56/3 or 18.6667
x2 + 7x = 0 => x*(x + 7) = 0 => x = 0 or x + 7 = 0 so that x = 0 or x = -7
x2-4x-21 = 0 => x = -3 or x = 7 x2-3x-18 = 0 => x = -3 or x = 6
To solve the expression (15x(7-7)(5 \times 2)), first simplify the term inside the parentheses: (7 - 7 = 0). This means the entire expression becomes (15x \times 0 \times (5 \times 2)). Since any number multiplied by zero is zero, the final result is (0).
25-7=18 18/3=6
5/6-7/18
b + 7 = 18 subtract 7 from each side b + 7 - 7 = 18 - 7 b = 11 ----------------check in original equation 11 + 7 = 18 18 = 18 --------------checks

x2 + 7x = 0 => x*(x + 7) = 0 => x = 0 or x + 7 = 0 so that x = 0 or x = -7
x2-4x-21 = 0 => x = -3 or x = 7 x2-3x-18 = 0 => x = -3 or x = 6
5t - 7 = 11 5t - 7 + 7 = 11 + 7 5t = 18 5t/5 = 18/5 t = 18/5 t = 3 3/5
There is a formula for "the difference of squares." (x + 7)(x - 7) = 0 x = 7, -7
when you divide any number by 0, ie (18-7), the number will always be undefined. It does not matter if it is 11, 0, or 100000.

5x - 7=18 you add the seven to 18 and get 25 then you divide 25 by 5 to get x by itself and you will get 5 x=5
No, 18 does not go into 7 evenly. When you divide 7 by 18, the result is 0 with a remainder of 7. In other words, 18 cannot be divided into 7 without having a leftover amount.
