System of equation consists of two or more equations with unknow variables. A possible step used in eliminating the y-term is (y + z 6) *5
<h3>System of equations</h3>
System of equation consists of two or more equatons with unknow variables.
Given the system of equations
y + z = 6
5y + 9z =1
In order to eliminate the variable "y", we <em>will multiply equation 1 by 5 and subtract from equation 2;</em>
5y + 5z = 30
5y + 9z = 1
Subtract
5z - 9z = 30 - 1
-4z =29
This leaves only the variable "z" eliminating variable. "y"

Answer:
exact form os -25/36
Step-by-step explanation:
Answer:
$39.36
Step-by-step explanation:
Since its 20% off that means we still have a remaining 80% so first multiply 0.8 to the 82
82x0.8= 65.6
Since there is a additional 40% off multiply by 0.4 to get the discount amount
65.6x0.4= 26.24
Subtract the discount from the price
65.6-26.24= 39.36
Answer:
h(5) = 15
Step-by-step explanation:
h(x) = -2 + 5
h(5) = -2(5) + 5(5)
h(5) = -10 + 25
h(5) = 15
