Answer:
x=3
Step-by-step explanation:
Step 1: you have to replace y with x-6 to make it all one equation (as seen in the picture below)
Step 2: write it all together so: x-6= -2x+3
Step 3: add 2x on both sides to cancel out the negative so: x+ 2x and -2x+2x
Step 4: add 6 on both sides to cancel out the negative so: -6+ 6 and 3+6
Step 5: divide 3 by 3x and 9 to get x
Answer:
Step-by-step explanation:
we know that
The solution of the system of inequalities is the shaded area below the solid line and below the dashed line
The equation of the dashed line is
The equation of the solid line is
therefore
The system of inequalities is
