8÷7=z and z is the answer you got when you divided,that's how I understand the question
Answer:
small number = -3
large number = 12
Step-by-step explanation:
Suppose two numbers are x and y
smaller number = x
larger number = y
Given that,
The difference of two numbers is 15
<h2>Equation 1</h2><h3>y - x = 15</h3>
Five times the smaller is the same as 9 less than twice the larger.
<h2>Equation 2</h2><h3>5x = 9 - 2y</h3>
Solve them
-x = 15 - y
x = y -15
put value of x in equation 2
5(y - 15) = 9 - 2y
-75 + 5y = 9 - 2y
-75 - 9 = -2y - 5y
-84 = -7y
y = 84/7
y = 12
x = 12 - 15
x = -3
Answer:
(-2,3,10,8)
Step-by-step explanation:
eg
(x,y)=(domain,range)
x components are domain and y components are range in the given set of ordered pairs
Answer:
wish it was that easy son
Step-by-step explanation:
.........................
We can solve for x in by substituting 'y=15-5x' from the second one into the first equation, because in the second equation, y has no coefficient, which will make it easier to substitute.
