Answer:
The value of x = 1.5
Step-by-step explanation:
Given:
-1.2(3 – x) = -1.8
To Find:
x = ?
Solution:
Distributive property:
The distributive property lets you multiply a sum by multiplying each addend separately and then add the products.
For example A(B + C) = A×B + A×C
Here we have,
-1.2(3 – x) = -1.8
Applying Distributive property we get ,
-1.2×3 -1.2×-x = -1.8
∴ -3.6 +1.2x = -1.8
∴ 
∴ x = 1.5
Answer:
1 unit to the right
Step-by-step explanation:
The y-axis is the vertical line and the point (1,-3) is one unit to the right of the vertical line
Answer:
Step-by-step explanation:
3x – y + 2z = 6 - - - - - - - - - 1
-x + y = 2 - - - - - - - - - - - - -2
x – 2z = -5 - - - - - - - - - - - -3
From equation 2, x = y - 2
From equation 3, x = 2z - 5
Substituting x = y - 2 and x = 2z - 5 into equation 1, it becomes
3(y - 2) – y + 2z = 6
3y - 6 - y + 2z = 6
3y - y + 2z = 6 + 6
2y + 2z = 12 - - - - - - - - - 4
3(2z - 5) – y + 2z = 6
6z - 15 - y + 2z = 6
- y + 6z + 2z = 6 + 15
- y + 8z = 21 - - - - - - - - - - 5
Multiplying equation 4 by 1 and equation 5 by 2, it becomes
2y + 2z = 12
- 2y + 16z = 42
Adding both equations
18z = 54
z = 54/18 = 3
Substituting z = 3 into equation 5, it becomes
- y + 8×3 = 21
- y + 24 = 21
- y = 21 - 24 = - 3
y = 3
Substituting y = 3 into equation 2, it becomes
-x + 3 = 2
- x = 2 - 3 = -1
x = 1
