2(2x)=4x
duh
4x=4x
x=x
true,
all real numbers are solutions
Hello!
To round to the nearest tenth, look at the number to the right of the tenths place (the number in the hundredths place). If it is a number from zero to four, you do not need to change the tenths place number. If it is a number from five to nine, you round the tenths place up a number.
For example:
0.34 rounded to the tenths place is 0.3 because the hundredths place is a four.
0.19 rounded to the tenths place is 0.2 because the hundredths place is a nine.
I hope this helps :))
You need to set this up with a proportion and solve. 18/x-5 = 13.5/12.
cross multiply 13.5x-67.5=216
now solve for x
13.5x=283.5
x=21
the missing side is equal to 21-5, which is equal to16

Step-by-step explanation:
You want to eradicate one pair of variables so they are set to zero. It does not matter which pair is selected:
{½[4x + 2y = 6]
{−2x + 2y = 18
