Equation 1) y = -3/2x + 9
Equation 2) 2x + 2y = 16
Add 3/2x to both sides of equation 1.
1) 3/2x + y = 9
Then, multiply all of equation one by 2.
1) 2(3/2x + y = 9)
1) 3x + 2y = 18
2) 2x + 2y = 16
Subtract.
x = 2
Plug in 2 for x in the first equation.
y=-3/2x+9
y = -3/2(2) + 9
y = -3 + 9
y = 6
So, x=2 and y = 6

Answer:
d = 9
Step-by-step explanation:
Calculate the slope of ab then equate to 3.
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (4, 6) and (x₂, y₂ ) = (d, 21)
m = 
= 
= 3 ( multiply both sides by d - 4 )
3(d - 4) = 15 ( divide both sides by 3 )
d - 4 = 5 ( add 4 to both sides )
d = 9
