What is the value of 50 - 3 (x² - Y?) + x when

x = 6, and y = - 4?

- 64

Step-by-step explanation:

Given

50 - 3 (x² - y) + x ← substitute x = 6, y = - 4 into the expression

= 50 - 3 (6² - ( - 4)) + 6 ← evaluate the parenthesis

= 50 - 3 (36 + 4) + 6

= 50 - (3 * 40) + 6

= 50 - 120 + 6 ← evaluate from left to right

= - 70 + 6

= - 64

Answer: - 64
