When we say "solve for the variable", we mean to solve the equation because the solution of the equation is finding the unknown variable.
So, the similarity between "solving for a "variable" to "solving an equation" is that both actions imply looking at the value of that variable.

On the other hand, a slight difference would be in the case of having several variables in the equation. In this case, both actions could represent slight differences, because if we have three different variables and we say "solve for <em>y</em>", that means we must isolate that variable, and the result is just an expression. But, if we say "solve the equation"

Answer:
-3
Step-by-step explanation:
we take two points to find slope m
lets take ( 1, 4) and ( 2, 1)
then m=(1-4)/(2-1)
m=(-3)/(1)
m= -3
2x + 7 ≤ 3x - 5
Start by keeping the variable x on the left side of the inequality, and move everything else to the right side.
We can do this by subtracting 3x from both sides and subtracting 7 from both sides.
-x ≤ -12
Divide both sides by -1 to make x a positive; when dividing by a negative number you will flip the inequality sign, so ≤ becomes ≥.
x ≥ 12
Possible solutions for x are any number equal to or greater than 12.
