Solve the equation, justify each step with an algebraic property:
-8=-18+2x
1 answer:
-8 = -18 + 2x....addition property....add 18 to both sides
18 - 8 = 2x...simplify
10 = 2x....division property...divide both sides by 2
10/2 = x....simplify
5 = x

ur welcome ♥️♥️♥️
(67 + 68 + 78 + x) / 4 = 70
(213 + x) / 4 = 70
213 + x = 70 * 4
213 + x = 280
x = 280 - 213
x = 67
(213 + x) / 4 = 79
213 + x = 79 * 4
213 + x = 316
x = 316 - 213
x = 103
lowest u can make is 67, highest u can make is 100
