Answer:
The value of x=-2 and the value of y=5
Step-by-step explanation:
we have
Y=-4x-3 -----> equation A
y= -2x + 1 -----> equation B
Solve the system of equations by graphing
Remember that the solution is the intersection point both graphs
using a graphing tool
The intersection point is (-2,5)
see the attached figure
therefore
The value of x=-2 and the value of y=5

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
