Step-by-step explanation:
(6,4)
3x-1y=14
-y= 3x-14
y=-2x+16
sub in first equation
3x-14 =-2x+16
3x+2x= 16 +14
5x = 30
x = 6
plug in x
y=-2x+16
y = -2(6)+16
y = 4

Step-by-step explanation:
Answer:
No they are not equal;
a = -13
Step-by-step explanation:
Here, we want to find the value of a
We are gong to use the ratio given
That will be;
a + 3/ 7 + a = 4/5
5(a + 3) = 4(7 + a)
15 + 3a = 28 + 4a
4a - 3a = 15-28
a = -13
