Answer:
{y,x} = {-6,-2}
Step-by-step explanation:
/ Solve equation [2] for the variable y
[2] y = 2x - 2
// Plug this in for variable y in equation [1]
[1] (2x-2) - x = -4
[1] x = -2
// Solve equation [1] for the variable x
[1] x = - 2
// By now we know this much :
y = 2x-2
x = -2
// Use the x value to solve for y
y = 2(-2)-2 = -6
( -18 - 14)/(2 - -6)
-32/8
-4
[1] y = -x + 5
3x + 3•(-x +5) = 10
0 = -5 => NO solution
Answer:
3
Step-by-step explanation:
just plug in 9 to b
9x2=18 18-15=3
