3y+2z
It is the same as 8y+8z
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
is eassy
Expand z plus 11 times z plus 11 = (z+11)(z+11) = z2 + 22z + 121.
3a * * * * * Actually, it is 4a.
If you simplify the equation (s+t+s) the answer is 2s+t
True
When you simplify 49 plus 37 (49+37), the result is 86.
