Х is the first <span>integer
</span>(x+1) is the second integer
x + x + 1 = -49
2x + 1 = - 49
2x = -49 - 1
2x = -50
x = -25 first integer
-25 + 1 = -24 second integer
Answer: -25 and -24
Answer:
140
Step-by-step explanation:
Suppose,
x drinks were sold for 2$
y drinks were sold for 5$
therefore, x+y = 250....( 1 )
and 2x+5y = 830......( 2 )
multiply equation ( 1 ) with 2,
2x+2y = 500......( 3 )
Subtract equation ( 3) from (2)
3y = 330
or, y = 110
so, x = 140
so, 140 drinks were sold for 2$
Answer: 77
Step-by-step explanation:
To get standard form we need to move variables with their coefficients on one side and numbers on other side. Standard form looks like this:
Ax + By = C
y - 4 = 3x/4 +6
y - 3x/4 = 6+4
y - 3x/4 = 10
