1. –9x – 5 = –95
a) 17
b) 11
c) 10 <-----------------------------
d) –10
2.– 10 = –12
a) –6
b) –66 <---------------------------
c) 6
d) 66
To solve these equations, we need to isolate the variable (x) on one side of the equation. Let's start with the first equation:
1. –9x – 5 = –95
Adding 5 to both sides of the equation to cancel out the -5 on the left side:
–9x = –90
Now we need to isolate x, so we divide both sides of the equation by -9:
x = –90 / -9
Simplifying this expression:
x = 10
So the answer is c) 10.
Let's move on to the second equation:
2. –10 = –12
Since there is no variable on the equation, this equation is already solved for a single value. In this case, the equation is saying that -10 is equal to -12, which is false. There is no value that can make this equation true.
Therefore, there is no answer to this equation.
1 correct
2 I think you are missing an x somewhere in the equation.
