5+3*=8
8-2=6
* all you do is plug in the 3 for the x.
You also use PEMDAS to solve (the order to solve)

Given a value of x, find the value for -3x + 2
7h - 2 - 51 is an expression NOT an equation. An expression cannot be solved for the value of a variable.
It would help if the expression was given!
It is 25.
That word "equals" in there makes it an equation.

2 squared is 4 3 cubed is 27 27 plus 4 is 31
2(2)2 + 3(2)(- 4) - 4(- 4)2 8 - 24 - 64 = - 80 ======
