Answer:
1
Step-by-step explanation:
I would use elimination. I would multiply 4x+3y=2 by 3 so the it becomes 12x+9y=6, and I would multiply the bottom equation by 4 so that it becomes 12x+8y=4. Because I am using elimination I have to get rid of one variable, I chose to get rid of X hence that the coefficient of X in each equation is now 12. i simply subtract both equations and get y by itself. y=2. I plug in Y to find x in either of the original equations, where I get x=-1. To check my work substitute the values of x and y in the other equation. 4(-1)+3(2)=2 -------> 2=2
Answer:
The numbers are 19,20 and 21
Step-by-step explanation:
Let
x -----> the first consecutive number
x+1 ---> the second consecutive number
x+2 --> the third consecutive number
we know that
x+(x+1)+(x+2)=60
Solve for x
3x+3=60
3x=57
x=19
so
x+1=19+1=20
x+2=19+2=21
therefore
The numbers are 19,20 and 21
