The solution of system of equations is: x = 1.6 and y = 1.2
Step-by-step explanation:
Given equations are:
Putting in equation 2
Putting x = 1.6 in equation 2
Dividing both sides by -3
Hence,

To find the area of a triangle, multiply the base by the height, and then divide by 2. The division by 2 comes from the fact that a parallelogram can be divided into 2 triangles. For example, in the diagram to the left, the area of each triangle is equal to one-half the area of the parallelogram.
<span>-3 (4+3x)= -(3x - 48)
-12+9x = -3x+48
9x+3x = 48+12
12x = 60
x = 60/12
x = 5
So, your answer is 5</span>
