Substitute x = 6y + 21 into the first equation:-
6(6y+21) + 2y = 26
36y + 126 + 2y = 26
38y = -100
y = -2.63
x = 6(-2.63) + 21 = 5.22
answer (-2.63, 5.22) to nearest hundredth

Answer:
x = -2
y = 10
Step-by-step explanation:
(0.3 + 0.7) x + (0.4 - 0.8) y = 0.8 - 6.8
x - 0.4 y = -6 → x = 0.4 y - 6
0.3 ( 0.4 y - 6) + 0.4 y = 0.8 → 0.12y +0.4y - 1.8 = 0.8
→ 0.52 y = 2.6 → y = 2.6/0.52 = 10
x - 0.4(10) = -6 → x = -2
Answer:
The slope is zero
Step-by-step explanation:
(7-7)/(5+1)= 0/6= 0
No solutions would be correct so 0
