Answer:
4x - 7y = 19
4(-4) - 7(-5) = 19
-16 - (-35) = 19
-16 + 35 = 19
19 = 19
(-4,-5) is a solution to given equation.
4(9) - 7(6) = 19
36 - 42 = 19
-6 ≠ 19
(9,6) is not a solution to given equation.
4(1) - 7(-3) = 19
4 - (-21) = 19
4 + 21 = 19
25 ≠ 19
(1, -3) is not a solution to given equation.
4(-6) - 7(2) = 19
-24 - 14 = 19
-38 ≠ 19
(-6,2) is not a solution to given equation.

Answer:
answer is 3ZSM 1
Step-by-step explanation:
it has a Brainly question for something experimentable:-)
We can turn this into an equation.
if x stands for the number you are looking for, then
18 + 1/4 x = x
we can solve this equation
18 + 1/4 x = x
subtract 1/4x from both sides
18 = 3/4 x
divide both sides by 3/4
24 = x
2(5x + 2 + x) = 12x + 4 - Keep that in mind.
A. 10x + 6 = 2(<span><span>5x</span>+3</span>)
B. 12x + 4 = 4(<span><span>3x</span>+1</span><span>)
</span>C. 2(5x + 3) = 10x+6
D. 2(6x + 2) = 12x+4
In short terms, your final answer would be D.
2x+20 ≤ 119-9x *Move a constant (without a variable) to the opposite side*
