Answer:
x = 45/17
Step-by-step explanation:
We can move all x to 1 side and all the numbers to another. You can add 8.7 on both sides and get that 2.3x = 0.8x + 4.5. Next, we subtract by 0.8x on both sides to get that 1.7x = 4.5, where we can then divide by 17/10 on both sides to get that x is equal to 45/10 * 10/17, so that means that x = 45/17.
- 3 ( x - 1 ) = 18
- or, 3x - 3 = 18
- or, 3x = 18 - 3
- or, 3x = 15
- or, x = 15 ÷ 3
- or, x = 5

Answer:
0.6
Step-by-step explanation:
Positive is right and Negative is left. Move from 0 right to 1.4 and then move left 0.8 units to end up at 0.6
2 consecutive even integers : x and x + 2
4(x) + 3(x + 2) = 20
4x + 3x + 6 = 20
7x + 6 = 20
7x = 20 - 6
7x = 14
x = 14/7
x = 2
x + 2 = 2 + 2 = 4
so ur first number (x) = 2 and ur second number (x + 2) = 4
