Answer:
x = 1 and x = -7
Step-by-step explanation:
Given that,
...(1)
and
y = 7 -x ....(2)
Put the value of y from equation (2) in (1)
So,
x = 1 and x = -7
Hence, the solution of the given equations is x = 1 and x = -7
Answer:
Option A is the correct answer
A.
Step-by-step explanation:
let x be the first number,
so, the next two are (x+ 1) and (x+2)
x + 2(x +1) = 62 - 3(x + 2)
x + 2x + 2 = 62 -3x - 6
3x + 2 = 62 - 3x - 6
3x + 3x = 62 - 6 - 2
6x = 54
x = 9
so, three consecutive integers are
9, 10, 11
Hope this helps!
Answer:
Step-by-step explanation:
<u>Solve equation</u>
- 3x - 5 = 4 + 2x
- 3x - 5 - 2x + 5 = 4 + 2x - 2x + 5
- x = 9
