Solve the system y = - x + 7 and y = 0.5 (x - 3) 2

Show all work

x=5, y=2

Step-by-step explanation:

since y = - x+7

substitute it in the second equation to get; - x+7 = 0.5 (x-3) 2

then solve the equation

which would be - x+7 = x-3

because 0.5 * 2=1

when you connect the like terms you would get:-x-x=-3-7

which is equals to: - 2x=-10

which would make x = 5

so just substitute x in equation 1 for 5 which would give

y = - 5+7

so y = 2
