Answer: 6/5 and -6/5
Step-by-step explanation: In order to solve this problem, we want to get the variable on one side. In order to do that, we must do the following:
Add 36 on Both Sides:
Divide 25 on Both Sides:
Take the square root of Both Sides:
That means your answer is:
, or
Answer:
The value of 7w - 8 is -22
Step-by-step explanation:
Let us solve the question
∵ -4w - 5 = 3
→ Move -5 from the left side to the right side by adding both sides by 5
∴ -4w - 5 + 5 = 3 + 5
∴ -4w = 8
→ Divide both sides by -4
∵ =
∴ w = -2
→ Now let us find the value of the given expression
∵ The given expression is 7w - 8
→ Substitute w by -2 to gets its value
∴ 7w - 8 = 7(-2) - 8
∴ 7w - 8 = -14 - 8
∴ 7w - 8 = -22
∴ The value of 7w - 8 is -22
