Use substitution
Since you know y = 2, you can plug in 2 for y in the first equation
2 = 4x - 10
12 = 4x
x = 3
The solution is (3,2)
X = 3, y = 2
Answer:
the answer is 4
Step-by-step explanation:
if y=21 the we substitute in the main equation
21=8x-11
8x=32
x=4
Up 7 units, left 3 units
Or the vector (-3,7)
The answer is C. 8 minus 5 is 3 then 3 times 5 is 15.
