Step-by-step explanation:
Put the value y.
-2x-8(-5x+22)=14
-2x+40x-176= 14
38x-176 =14
38x = 190
x=5
Now put the value of X to find Y
Y= -5(5)+22= -25+22 = -3
=>X=. 5
=>Y= -3
9/10 is bigger. 10/10 is a whole so in decimal 9/10 is .90
steps
(x) = 5x^2-3x+7
refine
x=5x^2-3x+7
Switch sides
5x^2-3x+7-x=x-x
Subtract x from both sides
5x^2-4x+7=0
Solve with the quadratic formula
