Answer:
(-7, 5)
Step-by-step explanation:
Since both of them are equal to y, you could just set them equal to each other.
5/7x + 4 = -1/7x - 2
6/7x = -6
x = -7
Now just plug x back to one of the equations:
y = -1/7*(-7) - 2 = 7 - 2 = 5
Therefore, the solution to the system is (-7, 5)
Step-by-step explanation:
3(2x - 4) - 2(5x - 2) = -20
6x - 12 - 10x + 4 = -20
-4x - 8 = - 20
-4x = -20 + 8
-4x = -12
x = -12 ÷ -4
x = 3

Answer:
Step-by-step explanation:
6 11/12-(24 1/6+3 2/3)
=(6×12+11)/12-[(24×6+1)/6+(3×3+2)/3]
=(72+11)/12-[(144+1)/6+(9+2)/3]
=83/12-[145/6+11/3]
=83/12-[(145+2×11)/6]
=83/12-[167/6]
=83/12-334/12
=(83-334)/12
=-251/12
=-20 11/12
