Answer:
x=3
Step-by-step explanation:
5x-7=8
add seven to both sides
5x=15
divide by 5
x=3
Answer:
26 and 27
Step-by-step explanation:
The first integer = x
Therefore the second integer = x + 1
according to the statement we obtain the equation
(x) + (x + 1) <55
x + x + 1 <55
2 * x + 1 <55
We subtract 1 from both sides, we get:
2x <54
divide both sides by 2 we get:
x <27
Therefore the first integer is 26, since it has to be better than 27.
the second integer = x + 1
= 26 + 1
= 27
If we add 26 + 27 = 53, which is less than 55 and the condition is met
What do you mean? Is that the whole question?
Answer:
x=16
y=40
Step-by-step explanation:
x + y = 56
y = 56 - x (isolate a variable)
y = -x + 56 (this is optional)
2x = .5y + 12
2x = .5(-x + 56) + 12 (substitute for y)
2x = -.5x + 28 + 12
2x = -.5x + 40
2.5x = 40
x = 16
16 + y = 56 (plug what you got for x back into the original eq)
y = 40
