Step-by-step explanation:
try math caculators to help you with these questions thats where i go the solution from.
-Best of luck
Do you mean like this?
Y = -x - 4
Y = x
x = -x - 4
2x = -4
x = -2
Therefore y = -2
7(12 1/3) + 8(12 1/3 + 1/4) = 3(6(12 1/3) - 9) - 8
12 1/3 = 12.33
1/4 = 0.25
7(12.33) + 8(12.33 + 0.25) = 3(6(12.33) - 9) - 8
86.31 + 8(12.58) = 3(73.98 - 9) - 8
86.31 + 100.64 = 3(64.98) - 8
186.95 = 186.94 - 8
186.95 ≠ 178.94
False. The x, when 12 1/3 does not work inside this equation
