SOLUTION: 10=7-(3+x) 10 = 7 + -1(3 + x) 10 = 7 + (3 * -1 + x * -1) 10 = 7 + (-3 + -x) 10 = 4 - x 10 - 4 = 4 - 4 - x 6 = -x x = -6

Algebra ->  Numeric Fractions Calculators, Lesson and Practice -> SOLUTION: 10=7-(3+x) 10 = 7 + -1(3 + x) 10 = 7 + (3 * -1 + x * -1) 10 = 7 + (-3 + -x) 10 = 4 - x 10 - 4 = 4 - 4 - x 6 = -x x = -6      Log On


   

Question 781255: 10=7-(3+x)
10 = 7 + -1(3 + x)
10 = 7 + (3 * -1 + x * -1)
10 = 7 + (-3 + -x)
10 = 4 - x
10 - 4 = 4 - 4 - x
6 = -x
x = -6
