Answer:
2
Step-by-step explanation:
You can ask yourself different ways to solve these kinds of problems.
I start with “Can the lowest number go evenly into the largest?”
The answer for this is no. So you work down the vine.
What do these numbers have in common? They are even!
What can all even numbers be divided by?
2!
7x + 9y = - 27_________eq1
3x - y = 3__________eq2
Multiply eq 2 by 9 and then add the resulting eq with eq1.
eq2 x 9 gives us 27x - 9y = 27___________eq3
add eq3 with eq1 we get.
34x = 0.
where x=0/34
x=0.
substitute x into any of the above equations to get y.
substitute x into eq1. we get:
7(0) + 9y =-27
9y = -27
y= -27/9
y = -3.
Answer:
m = 1
Step-by-step explanation:
1x is the slope without the 'x', it's 1.
1 subtract 1 2m - 1 = 3m
<span>2 subtract 2 2m = 1 + m </span>
<span>3 subtract m m - 1 = 2 </span>
<span>4 add 2 + m = 3 </span>
<span>5 subtract 2m -2 + m = 1 </span>
<span>6 add 1 3 = 1 + m
