3x - 4y = 10
-3x - 4y = 8 -> add line 1 to line 2 3x - 4y = 10
0x - 8y = 18 -> -8y = 18 -> y = -18/8 = -9/4 -> 3x - 4*(-9/4) = 10 -> 3x + 9 = 10 -> 3x = 1 -> x = 1/3
An equation?
The equation is -2y + 16 = 10
That word "equals" in there makes it an equation.

If a statement includes an "equals" sign ( = ) then the statement is an equation. By the way . . . it may or may not be a true statement. "10 equals 120" is not true.
That word "equals" in there makes it an equation.
x = sqrt 100

Log 200=a can be converted to an exponential equation if we know the base of the log. Let's assume it is 10 and you can change the answer accordingly if it is something else. 10^a=200 would be the exponential equation. For a base b, we would have b^a=200
Divide each side of the equation by 10 .
A two-step equation that equals 30 could be 2x + 10 = 30. In this equation, you would first subtract 10 from both sides to isolate the variable: 2x = 20. Then, you would divide both sides by 2 to solve for x: x = 10. Therefore, the solution to the equation 2x + 10 = 30 is x = 10.
