Answer:
y=0x+2
Step-by-step explanation:
-7x+y=42
y=42+7x
5x+13y=66
Substitute for y (meaning put 42+7x into the equation above instead of y because they are equal - see second line of my answer above)
5x+13[42+7x] = 66
5x +546 = 66
5x=66-546
5x=-480
x=-480/5
x=-96
Answer:
y=3x+2
Step-by-step explanation:
3x - y = -2
-3x -3x
_________
-y = -3x-2
/-1 /-1
_________
y = 3x+2
Answer:
5, 48, 4, 32, 3, 24
Step-by-step explanation:
do not get intimidated by this question , its very easy
let's break it ike this, 543 x 18
get the bigger number first , 543
each digit will be multiply by the opposite number which it's 18
READY? watch! 543 ( we'll separate them)
1. 5x (18) we'll break the 18 watch. 1 and 8 and we'll multiply each by 5
<u>5</u>x1= 5
5x8= 48.
2. 4x 18
<u>4</u>x1=4
4x8=32
3. <u>3</u>x 18
3x1=3
3x8= 24
