The sum is the answer to an addition problem. Since we know the sum involves addition, we write an addition equation between the variable and the number given to us.
6 + n (number that was not given to use) = 23
Any number larger than 36 would be a counter examples.
When n is equal to 36, both sides of the inequality are equal to 216. As you get larger than 36 the right side is larger than the left side. Therefore, the inequality is not true.
Equation: 26=6(5−4f)
Step 1: Simplify both sides of the equation.
26=6(5−4f)
26=(6)(5)+(6)(−4f)(Distribute)
26=30+−24f
26=−24f+30
Step 2)Flip the equation.
−24f+30=26
Step 3)Subtract 30 from both sides.
−24f+30−30=26−30
−24f=−4
Step 4) Divide both sides by -24.
-24/-24f=-4/-24
f=1/6
