1 solution; (1,4)
Step-by-step explanation:
Whenever two lines intersect, their solution is the point that the two share in common. Here, it's (1,4), so that is the answer.
Answer:
Step-by-step explanation:
-2x + 3y = 6.....(x, -4)...so y = -4
-2x + 3(-4) = 6
-2x - 12 = 6
-2x = 6 + 12
-2x = 18
x = -18/2
x = -9
so the value of x is -9.....(-9,-4)
Answer:
It's a proportion.
2 is to x as 15 is to 9, or 2/x = 15/9.
Multiply the means and extremes
15x = 18
divide both sides by 15 to get x by itself.
x = 1.2
