Negative four times 3p is -12p so then -12p-7 <5. Then add 7 to five and get -12p<12. Divide by -12, change direction of symbol because you are dividing by a negative and get p>-1.
No because if it was no solution you would put I solution or a 0 with a line through it. 0 is still a number just like -1 -2 and -3 are still a number;) hope this helps
Answer:
33
Step-by-step explanation:
The solution to the equations x - 4y = 0, x - y + 3z = 3 and 2x - 3y - z = -7 is x = -4, y = -1 and z = 2
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Independent variables represent function inputs that do not depend on other values, while dependent variables represent function outputs that depends on other values.
Given the equations:
x = 4y
x - 4y = 0 (1)
Also:
x - y + 3z = 3 (2)
And:
2x - 3y - z = -7 (3)
The solution to the equation is:
x = -4, y = -1 and z = 2
The solution to the equations x - 4y = 0, x - y + 3z = 3 and 2x - 3y - z = -7 is x = -4, y = -1 and z = 2
