3(4x-2)=12x-6 has infinite many solutions
3(4x-2)=-12x-6 has one solution, x=0
-3(4x-2)=-12x-2 has no solution.
Set up a proportion.
30/6 = 300/x
Cross multiply:
6 * 300 = 30 * x
1800 = 30x
Divide 30 to both sides:
x = 60

Answer:
30
Step-by-step explanation:
x(y+4) x=5 and y=2
so substitute the values for the variables
5(2+4)
Order of Operations : Parentheses first
5(6)
=30
or distributive property
5(2) +5(4)
10+20
=30
You get the same answer anyway.
Hope this helped :)
