Answer:
5/21
Step-by-step explanation:
2/7 * 5/6 = 2 * 5 / 7 * 6 = 10 / 42 = 5/21
So if you're solving by substitution, one equation must be in slope intercept form. Ill just go with the first one.
-4x+y=6
<u>+4x +4x
</u>y=6+4x
Now substitute the value of y in for the value of y in the second equation:
-5x-(6+4x)=21
-5x-6-4x=21
-9x-6=21
<u> +6 +6
</u><u>-9x=27
</u>-9 -9
x=-3
Now input that into the first equation:
-4(-3)+y=6
12+y=6
<u>-12 -12</u>
y=-6
