What is the value of x in following system y=3x- 5. 6x+3y=15
2 answers:
X is 2
To find this, substitute the first equation of Y into the second equation, like this:
6x + 3 (3x - 5) = 15
Then, solve for x.
First, distribute the 3 into the parenthesis:
6x + 9x - 15 = 15
Then, combine like terms:
15x - 15 = 15
Add 15 to both sides to cancel out the -15
15x = 30
Now, divide by 15 on both sides to cancel out the 15 from the x.
x = 2x
Hope this helps!
