Answer:
x = - 7, y = 6
Step-by-step explanation:
7x + 7y = - 7 -----> equation 1
- 10x - 7y = 28 -----> equation 2
Add equations 1 & 2,
7x + 7y = - 7
- 10x - 7y = 28
___________
- 3x + 0 = 21
- 3x = 21
x = 21 / - 3
x = - 7
Substitute x = - 7 in equation 1,
7x + 7y = - 7
7y + 7x = - 7
7y + 7 ( - 7 ) = - 7
7y - 49 = - 7
7y = - 7 + 49
7y = 42
y = 42 / 7
y = 6
Answer:
C IS 100 F is 100 they usually give numbers to subtract but ion see it
A = 8
B = 50
Step-by-step explanation:
Let the number be X. Then we find
7X + 3 = 39 - 2X
Now we collect the terms and find
9X = 36
Finally we divide by 9
X = 4
So our answer is 4
So run then jump so for A it’ll be in the top right box start from zero then move your pencil 2 spaces , then move it up 2 spaces , then that’s your answer ! always remember run then jump ! <33 hope this helps
