Solve this system of equations using substitution: y = 2r - 4.
x + 2y = 10
Step 1: Substitute for y in the second equation. Which is the
resulting equation?
2x - 4 = 10
x + 2x - 4 = 10
x + 2(2x - 4) = 10

Five dinosaurs go for a walk and come across some lovely chicken wings. their names are rexy, bronto, steggy, paly, and terry. there are exactly 5 dozen wings(equal enough for each dino to have a dozen right? ); however, terry is on a diet and he only eats 6 wings. if paly eats 2 more than terry, steggy eats 4 more than paly, and bronto and rexy eat the same amount because they are really hungry from not eating all day, how many chicken wings did each dino eat?
