z2
3y+2z
z + 8 - 2 is an expression, not an equation. An expression cannot be solved. At best, you can simplify it to z + 6.
-4(7x-3y-z)-(-6)(9x-z+2)
You can't simplify it any further than 3x+2y+6z=24, unless you have been given values of x,y and z or other equations to find x,y and z.
simplify the square foor of 49 times x to the third time y to the sixth times the absolute value of z squared

Sure thing, honey. To simplify that expression, you just distribute the 8 to both terms inside the parentheses. So, you get 8y + 8z. That's all there is to it, darling.
Expand z plus 11 times z plus 11 = (z+11)(z+11) = z2 + 22z + 121.

If you simplify the equation (s+t+s) the answer is 2s+t
True
To solve the equation (2z + 1 - 3 = z - 2), first simplify the left side: (2z - 2 = z - 2). Next, subtract (z) from both sides to get (2z - z - 2 = -2), which simplifies to (z - 2 = -2). Finally, add 2 to both sides to find (z = 0).
