11
subtract 9 to both sides
Answer:
Step-by-step explanation:
Slope = 2 and passes point (4,7)
The equation is y - y1 = m(x - x1)
And y1 = 7 while x1 = 4, m = 2
: - y - 7 = 2(x - 4)
y - 7 = 2x - 8
y = 2x - 8 + 7
y = 2x - 1 this is the equation

Step-by-step explanation:
Answer:
x=10, y=-5
Step-by-step explanation:
2x+3y=5, y= 5-x; change y to 5-x:
2x+3(5-x)=5
2x-3x+15=5
-x=5-15
-x=-10
x=10
=>y=5-x=5-10=-5
