Solve the equation. n over 10 plus space 7 space equals space 10

30

Step-by-step explanation:

Given the equation;

n/10 + 7 = 10

We are to find the value of n

Subtract 7 from both sides

n/10 + 7 - 7 = 10 - 7

n/10 = 3

Cross multiply

n = 10 * 3

n = 30

Hence the solution to the equation is 30

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
