Answer:
3 and -4
Step-by-step explanation:
this is simple but difficult
let the number be x and second number be y
3x + 2y=1
x-y/2=5
from the 2nd equation
x-y/2=5
x=5+y/2
substitute value for x into equation 1
3x + 2y=1
3(5+y/2) + 2y= 1
15 +3y/2 +2y=1
15 + 7y/2=1
7y/2= 1 - 15
7y/2=-14
cross multiply
7y= -28
y= -28/7
y= -4
therefore second number is -4
substitute value for y into 1st equation
3x + 2y=1
3x + 2(-4) = 1
3x - 8= 1
3x= 1+8
3x= 9
x= 9/3
x= 3
therefore first number is 3
therefore two numbers are;
3 and -4
Answer:
Step-by-step explanation:
2 + 32 = 5 + 3z
34 = 5 + 3z
3z + 5 = 34
3z + 5 - 5 = 34 - 5
3z = 29
3z ÷ 3 = 29 ÷ 3
Answer:
The answer and explanation is on the picture.
B: 83
explanation:
62+35=97
180-97=83
Answer:
The value of y will be 1/3.
Step-by-step explanation:
First take +5 to the right side of the equation and subtract from 10. Then divide the answer by 15 by taking the 15 multiplied to y to the right side.
