Answer:
8/9
Step-by-step explanation:
the equation is x = k / y
when x = 2 & y = 8 then k is 16
when you is 18 then x = 8/9
Okay:
For line “l”: y=4
For line “m”: y=-2/1+4
For line “p”: x=-4
For line “n”: y=1x-1
X=-2 and y=3.
The first step we take is to substitute the value for y from the second equation into the first equation:
4x+5(3x+9)=7
This is justified by substitution. The next step is:
4x+5*3x+5*9=7
4x+15x+45=7
This is justified by the distributive property. The next step is:
19x+45=7
This is justified by addition of like terms. The next step is:
19x+45-45=7-45
19x=-38
This is justified by the subtraction property of equality. The next step is:
19x/19 = -38/19
x=-2
This is justified by the division property of equality. The next step is:
y=3(-2)+9
y=-6+9
y=3
This is justified by substitution, multiplication and addition, in that order.
