Answer:
The three integers are 13,14,15
Step-by-step explanation:
Let x be the first integer
x+1 be the second integer
x+2 be the third integer
The sum of the three integers is 42
x+ (x+1) + (x+2) = 42
Combine like terms
3x+3 = 42
Subtract 3 from each side
3x+3-3 = 42-3
3x= 39
Divide by 3
3x/3 = 39/3
x = 13
x+1 = 14
x+2 = 15
The three integers are 13,14,15
Answer:
x=3, y=0.8
Step-by-step explanation:
8x+5y=28
4x+5y=16
Subtract the second simultaneous equation from the first.
You are left with: 4x=12
12/4=3
x=3
Substitute this back into one of the equations.
8(3)+5y=28
8*3=24
28-24=4
4=5y
4/5=0.8
y=0.8
Answer:
-3(x - 738)
Step-by-step explanation:
-3x+2214
-3x+3 . 738
-3(x-738)
