Firstly, you have yo multiply out the first bracket by multiplying (2x - 5) by 4. The equation would then look like:
8x - 20 = 5x - 20 + 3x
Then you have to put normal numbers on one side and x-terms on the other. It would look like:
-20 + 20 = 5x + 3x - 8x
Then you should solve the additions and subtractions
0 = 0x
Since ANY number multiplied by 0 is zero, your equation has infinite solutions.
Answer:

Step-by-step explanation:
combined they both equal 180
Answer:
x=2
Step-by-step explanation:
x + 4 = 3(3x - 4)
Distribute
x+4 = 9x -12
Subtract x from each side
x+4 -x = 9x-x-12
4 = 8x-12
Add 12 to each side
4+12 = 8x-12+12
16 = 8x
Divide by 8
16/8 = 8x/8
2 =x
1. 9.6 x 10^5
2. 2.2 x 10^-4
3. 1.200565885 x 10^8 or 1.2 x 10^8
