Subtract 3x from both sides then isolate the variable.
Sooooo...

5x + 7 = 3x - 5

First, subtract 3x from both sides.
5x = 7 - 3x = -5
Second, keep the 7 and subtract the 5x - 3x to get 2x.
2x + 7 = -5
Third, subtract the 7 from both sides.
2x = -5 - 7
Fourth, simplify -5 - 7.
2x = -12
Fifth, take the 2 and divide it on both sides, leaving just x in its place.
x =  -\frac{12}{2}
Sixth, since 6 goes into 2 to get 12, simplify the fraction to 6.
x = -6

Answer: x = -6

Five angles of a hexagon measures 119, 129,104,139 and 95 degrees. What is the measure of the sixth angle?
Kisachek [45]

Answer:

x = 134

Step-by-step explanation:

Given that,

Five angles of a hexagon measures 119, 129,104,139 and 95 degrees.

We know that,

The sum of interior angles of a hexagon must equal 720 degrees.

So,

119+129+104+139 +95+x = 720

Where

x is the sixth angle

So,

586+x=720

x = 720-586

x = 134

So, the sixth angle is equal to 134.

What's 7/12 minus 3/12 simplified? BTW ONLY IN 4TH GRADE MAKE IT CLEAR
dusya [7]
7/12 - 3/12 = 1/3
Simplify each fraction if possible.
Same denominator? YES!
7 - 3 = 4
Since they have the same denominator, you just subtract the numerators.
Then simplify 4/12
4/4= 1 12/4= 3
Answer: 1/3
Hope that helps!
