Answer:
x=3
Step-by-step explanation:
minus 3x on both sides
after you've subtracted 3x from both sides you then need to minus 12 from both sides
Last step is going to be dividing by 2 and you should get the answer of 3
Answer:
10 subtracted from the product of 8 and 'a' is equal to the product of 6 and 'a'
Step-by-step explanation:
Answer:
x=4
x=-5
Step-by-step explanation:
in order for this to be equal to 0, 1 or both of the factors has to be 0, because anything multiplied by 0 is 0.
123 * 29382 * 8139* 0 = 0
x-4 = 0
x = 4
x+5 = 0
x=-5
Quick steps to solve this.
1. Lets square both. (X +Y)*2 = 7*7
2. Then, X*2 + 2XY + Y*2 = 49
3. Since XY is given to 4, X*2 + 8 + Y*2 = 49
4. Move 8
5. X*2 + Y*2 = 49 - 8
6. X*2 + Y*2 = 41
The answer is "41" Boom!
