Answer:
{10, -4}
Step-by-step explanation:
(x-3)^2 = 49
Take the square root of each side
sqrt((x-3)^2) = sqrt(49)
x-3 = ±7
Add 3 to each side
x-3+3 = 3±7
x = 3±7
x = 3+7 and x = 3-7
x = 10 x = -4
Add, -11.5x and move it over to 8.5x
Then, subtract them together and you get 20x + 51.86 = 51.76
And you move (subtract) 51. 86 over to 51.76, subtract that and you get 20x = -0.1
Divide, and your answer is -200
Answer:
y = 70 and x = 20
Step-by-step explanation:
180 - 40 = 140
140/2 = 70
70 + 90 = 160
180 - 160 = 20
