On the left side of the equation, you have like terms : 2x and 4x
That means that you can combine them
2x+4x=3x+1
6x=3x+1
Now, since the 3x is on the other side of the equation, you have to perform the opposite operation by subtracting 3x on both sides of the equation:
The 3x's will cross out on the right side of the equation
3x-3x=0x=0
On the left side:
6x-3x=3x
SO, now the equation looks like:
3x=1
Now, to get x by itself, perform the opposite operation by dividing 3 on both sides of the equation:
The 3's will cross out on the left:
3x ÷ 3 = 1x = x
On the right:
1 ÷ 3 = 1/3
x=1/3
Third angle = 180 - (44 + 72) = 180 - 116 = 64 degrees answer
5t + (t - 3) - [(7t + 5) - (8 - 3t)] (multiply -1 to (8 - 3t)
5t + (t - 3) - [(7t + 5) - 8 + 3t]
5t + (t - 3) - [7t + 3t + 5 - 8]
5t + (t - 3) - [10t - 3] (multiply -1 to [10t - 3]
5t + (t - 3) - 10t + 3
5t + t - 10t - 3 + 3
-4t
answer
Answer:
e : g = 2 : 7
Step-by-step explanation:
e/f = 3/7
e = 3f/7
f/g = 2/3
g = 3f/2
e/g = (3f/7)/(3f/2) = 2/7
Answer:
Step-by-step explanation:
If you are solving x then do this:
-2.3-5=x-17
First combine like term.
-7.3=x-17
Then add each side of the equation by 17 (we aren't subtracting because we are trying to get rid of -17 so to get rid of it we add by 17).
-7.3 +17 = x-17+17
9.7=x
