To solve just isolate y from 2x-y=-1 to get y=2x+1. Then substitute y=2x+1 into 3x-2y=1. So it should be this: 3x-2(2x+1)=1. Distribute to get 3x+4x-2=1. Add the x's to get 7x-2=1, add two to both sides to get 7x=3 and divide to finally get x=3/7.
Answer:
14°
Step-by-step explanation:
4x + 32 + 64 = 180 => x = 14 (°)
A∩B = {2, 4}
Step-by-step explanation:
- Step 1: Given A = {1, 2, 4} and B = {2, 4, 6, 8, 10}
- Step 2: To find A∩B, find the number of common elements in both the sets.
⇒ A∩B = {2, 4}
16 486 000/21 280 000

77.5
Answer:
4
Step-by-step explanation:
2(10 -6x)=x -8x
20 - 12x = x - 8x
20 = x - 8x + 12x
20 = 5x
20 / 5 = x
x = 4
