Answer:
Step-by-step explanation:
The solution is the set of points where all the equations intersect. If there is no such point, there is no solution.
For example,
y = 8
y = 6
These are parallel lines with no points in common.
<span>2x − 3y − z
</span><span> x = −2,
</span><span> y = 3,
</span><span> z = −2
What we must do is replace the values given in the equation. We have then replacing:
</span> 2*(-2) - 3*(3) - (-2) = -11
The answer is -11
Answer:
1. True
2.False
3.False
4. False
5.True
6.False
Step-by-step explanation:
Answer:
x length
y width
2x=y
2x+2y=42/2
x+y=21 x+y=21
x+2x=21
3x=21/÷3
x=7
7+y=21
y=21-7=14
7×14=98 the area of a rectangle
