OK. If the x is a multiply symbol, -933

To simplify the expression (4x + 6x), you combine like terms by adding the coefficients of (x). This gives you (4 + 6 = 10), so the simplified expression is (10x).
13+-12--5 = 6

Same as subtracting 6 from 7 = K

z + 8 - 2 is an expression, not an equation. An expression cannot be solved. At best, you can simplify it to z + 6.
By multiplying out the brackets it then is -10+24t-48 = 24t-58 when simplified

To simplify the expression 18 + 7x - 12 + 5x, you first combine like terms. Combine the constants (18 and -12) to get 6. Then, combine the x terms (7x and 5x) to get 12x. Therefore, the simplified expression is 6 + 12x.
It is: 4b+6
