Answer:
(2, - 4 )
Step-by-step explanation:
Given the 2 equations
10x + 7y = - 8 → (1)
7x + 7y = - 14 → (2)
Subtract (2) from (1) term by term to eliminate y
(10x - 7x) + (7y - 7y) = - 8 - (- 14) , that is
3x = 6 ( divide both sides by 3 )
x = 2
Substitute x = 2 into either of the 2 equations and solve for y
Substituting into (1)
10(2) + 7y = - 8
20 + 7y = - 8 ( subtract 20 from both sides )
7y = - 28 ( divide both sides by 7 )
y = - 4
solution to the system of equations is (2, - 4 )
Answer:
Step-by-step explanation:
The linear term is always the one with only one x. Always.
-5x has only a single x as a factor.
So - 5x is the linear term.
Answer:
Just to be on the safe side the first #1 is 31.5 and the second #1 is 57.82
The quotient is 340 I know because I divided I changed .25 to 25 and changed 85 to 8500 then divided
