4,8 (x+4)=2,16
48 (x+4)=21,6
x+4=21,6/48
x+4= 0,45
x=0,45-4
x= -3,55
Answer:
x = -2
y = 6
Step-by-step explanation:
i multiplied the 1st equation by 3 and the 2nd by 5 to get the y-terms to zero out
12x + 15y = 66
+ <u>35x - 15y = -160</u>
47x = -94
x = -94/47
x = -2
substitute -2 for 'x' to solve for 'y':
4(-2) + 5y = 22
-8 + 5y = 22
5y = 30
y = 6
Answer:
117,449,953,338.
Step-by-step explanation:
(9,+9)0-2 = 0 - 2
= -2.
158932 x 738995
= 117,449,953,340
So the answer is
117,449,953,340 - 2
= 117,449,953,338.
1) 1 + 1 = 2
2) 1 - 1 = 0
3) 1 * 1 = 1
4) 1 / 1 = 1
Hope this helps!
