X = 15
X + 90 = 7x
X = 7x - 90
X - 7x = -90
-6x = 90
Divide both sides by -6
X = 15
I think the answer is 10, 20, and 4
ANSWER: The answer is c) -5 and a very happy birthday to you
Answer: The three different equations will be
Step-by-step explanation:
We have to write three equation that have x = 5 as a solution:
1) First equation will be
2) Second equation will be
3) Third equation will be
Hence, the three different equations will be
Let x be the number
5x = x + 5
subtract x from both sides
5x - x = 5
4x = 5
Divide both sides by 4
4x/4 = 5/4
x = 5/4
=======
Check:
5 * (5/4) = (5/4) + 5
25/4 = 1.25 + 5
6.25 = 6.25
