Answer:
5x + y = 9
3x + 2y = 4
-10x - 2y = -18
3x + 2y = 4
-7x = -14
x = 2
5(2) + y = 9
10 + y = 9
y = -1
(2, -1)
the answer is c
Step-by-step explanation:
Answer:
3x+5=23 is the answer
Step-by-step explanation:
because 3 markers for every person and we dont know how many people there are so that's x then you add 5 to the 3 time x and you should have 23 as your answer
Firstly there is no ones in those so
4.530
5.430
6.740
8.654
X=0
multiply both sides of the equation by 2
x= -5*.
multiply 2 by -5 to get -10
x= -10x
since -10x contains the variable to solve for, move it to the left side of the equation by adding 10x to both sides
x+ 10x = 0
add x and 10x to get 11x
11x=0
x=0
Answer: b
