Given the system of linear equations:
1 answer:
Answer:
(1,6)
Step-by-step explanation:
To solve by substitution, rearrange -x+y=5 to y=x+5 and substitute it into 4x+y=10.
4x + (x+5) = 10
4x+x+5=10
5x+5=10
5x=5
x=1
Now substitute x = 1 back in to find y.
y= (1) + 5
y=6
Solution is (1,6)
Verify substituting both values into each equation in to verify true.
-x+y=5
-(1)+6 = 5
-1+6=5
5=5 True
4(1)+6=10
4+6=10
10=10 True

126 ÷ 3= 42
42×2= 84 (number of cupcakes sold)
126-84= 42 (number of cupcakes left)
The two factors are 2 and p=10 so I used your equations and
You need to solve for x
12x2 - 13x + 3 = 0
24 - 13x + 3 = 0
27 - 13x = 0
27 = 13x
27/13 = x
your answer will be 27 over 13
The answer is C 36 in. Squared.
