Answer:
5, -⅓
Step-by-step explanation:
x = 2:
4x + 3y = 23
3y = 23 - 4(2)
3y = 15
y = 5
x = 6:
4x + 3y = 23
3y = 23 - 4(6)
3y = -1
y = -⅓
Answer:
No solution
Step-by-step explanation:
-9 + n = n - 1
-9 +1 = n -n
-8 = 0
No solution here if the proper rules of equation are correctly applied
S=k, a=4k-2
Annika rides her bike so she must travel some positive distance, ie a>0 so:
4k-2>0
4k>2
k>1/2 and that k is how far Sam rode, so Sam must ride his bike more than 1/2 kilometer.
The question is asking that X times 38% will equal to 247. So we set up the equation:

Then, we multiply both sides by

and we get the answer is
650
The equation is:
2/3n + 4 = 7
