solve the euation graphically . 4x-y =4 , 3x +2y =14
Answers
Answer:
Step-by-step explanation
4x - y = 4 3x + 2y = 14
→ if x = 0 → if x = 0
∴ 0 - y = 4 ∴0 + 2y = 14
y = -4 y = 14/2
y = 7
→ if y = 0 → if y = 0
∴ 4x - 0 = 4 ∴ 3x + 0 =14
4x =4 3x =14
x=4/4 x = 3/14
x = 1 x = 4
X = 0 1 X = 0 4.6
Y = - 4 0 Y = 7 0 (X,Y) = (0 ,-4 ) (1, 0) (X,Y) = (0 ,7 ) (4.6, 0)
