The first answer is x=63
the second one is x=10
Answer:
<em>y = 2x+6</em>
Step-by-step explanation:
Let the output value be y
Let the input value be x
the output of a function is 6 more than 2 times the input
2 times the input is expressed as 2x
6 more than 2 times the input is expressed as 2x + 6
Since the output of a function is 6 more than 2 times the input, we will equate y to the resulting equation to have;
y = 2x + 6
<em>Hence the required equation is y = 2x+6</em>

Answer:
Step-by-step explanation:
1. Expand by distributing sum groups.
2. Expand by distributing terms.
3.Expand by distributing terms.
4. Remove parentheses.
5. Collect like terms.
6. Simplify.
Thus. the answer is,
Answer:
when (-1, -4) is substituted into the first equation it's true
when (-1, -4) is substituted into the second equation it's true
the ordered pair (-1, -4) is a solution to the systems of equation
Step-by-step explanation:
original equation
x-y=3
multiply both sides by 7
7x-7y = 21
add 7y to both sides
7x=7y + 21
substitute into second equation
(7y+21)-y=-3
simplify
6y+21=-3
subtract 21 from both sides
6y=-24
y=-4
substitute y into original equation
x-(-4) = 3
cancel out negative signs
x+4=3
subtract -4 from both sides
x=-1
4k+44 = 10 k -10
-4k -4k
44 = 6k-10
+10 +10
54=6k
54/6 = 6k/6
9=k hope this helps
