Step-by-step explanation:
x greater than 9 AND x smaller than 9
x smaller than than 9 OR x greater than 9
x greater than or equal to 9 AND x smaller than or equal to 9
x smaller than or equal to 9 OR x greater than or equal to 9
I dunno if this is what you asked^^
Answer:
(5, )
Step-by-step explanation:
Given the 2 equations
5x + 7y = 40 → (1)
3x - 7y = 0 → (2)
Adding the 2 equations term by term will eliminate the y- term
8x + 0 = 40
8x = 40 ( divide both sides by 8 )
x = 5
Substitute x = 5 into either of the 2 equations and solve for y
Substituting into (1)
5(5) + 7y = 40
25 + 7y = 40 ( subtract 25 from both sides )
7y = 15 ( divide both sides by 7 )
y =
solution is (5, )
