Which ordered pair is a solution to the linear equation -3x+2y=4?
2 answers:
-x+y-3z+4w=6^"dfv
Answer:
Step-by-step explanation:
Substitute x= 0
-3(0) +2y = 4
2y = 4
y = 4/2
y = 2
and then substitute y=2 into eq.
-3x +2y = 4
-3x +2 (2) = 4
-3x +4 = 4
-3x = 0
3x = 0
x = 0
Check result: x = 0 y = 2
-3x + 2y = 4
-3 (0) + 2 (2) = 4
0 + 4 = 4
4 = 4 therefore x and y correct.
