Answer:
x = 29
y = 13
Step-by-step explanation:
Write 2 equations:
x + y = 42
x - y = 16
Isolate x in the first equation:
x = 42 - y
Substitute this in for x in the second equation:
42 - y - y = 16
42 - 2y = 16
solve for y:
-2y = -26
y = 13
Plug in 13 for y in either equation:
x + 13 = 42
Solve for x:
x = 29
Answer:
x-intercept (2,0) or x=2
y-intercept (0,-4) or y=-4
Step-by-step explanation:
4x-2y>8
2x-y>4
2x-4>y
y<2x-4
y=2x-4
when y=0
2x=4
x=2
x-intercept is (2,0)
and y-intercept is (0,-4)
put x=0,y=0
0-0>8
or 0>8 which is not true. so (0,0) does not lie on the graph.
so graph lies right of the line .

Step-by-step explanation:
3 + 3(k + 3) = 6(k - 2) + 9
3 + 3k + 9 = 6k - 12 + 9
12 + 12 - 9 = 6k - 3k
15 = 3k
k = 15/3
k = 5
