Answer: False
Reason: It should be x-a instead of x+a
Answer: x = -1 and y = -2
Step-by-step explanation:
You are given two expressions that have a relationship. There are two ways to solve this problem, but I will be going over the easy way. I'm assuming you know how to solve for one variable such as x? Well we can put the y varaible from the first equation in terms of x, from the second equation. Ill show you what I mean:
6x + 5(7x + 5) = -16
I replaced y in the first one in terms of x, so that we can solve just for x.
6x + 35x + 25 = -16
41x +25 = -16
41x = -41
x = -1
Now simply find y by plugging the now known x value into either equation
y = 7(-1) + 5
y = -2

Step-by-step explanation:
Answer:
x = 15, y = 4
Step-by-step explanation:
By Basic proportionality theorem, we have:
x/ 5 = 18/6
x = (18*5)/6
x = 90/6
x = 15
Again By Basic proportionality theorem, we have:
12/y = 18/6
y = (12*6)/18
y = 72/18
y = 4
