Answer:
Step-by-step explanation:
If y= x + 4 then plug it into the other equation where the y is. So 5x + x +4=22. Then solve.
for x for y
5x + x + 4=22 y=x +4
6x+4=22 y=3+4
22-4=18 y=7
6x = 18
18/6=3
x=3 so, x=3 and y=7
Answer:
y=3x-10
Step-by-step explanation:
gradient to the line y=3x+2 is same as that of the line passing through the point (2,-4)
gradient=3
( {y-(-4)}/{x-2} )=3
apply cross multiplication and the equation will be:y=3x-10
The correct answer is: B.
I think it would be 40 but that’s not a option so maybe 45?
