Question

4(2x-6)=3(5x+2) resultado de sustitución

Answer 1

4(2x-6)=3(5x+2)
8X - 24 = 15X + 6
8X - 15X = 6 + 24
-7X = 30 /•-1
7X = -30
X = -30/7

Sustituimos o reemplazamos
4(2x-6)=3(5x+2)
8X - 24 = 15X + 6
(8 • -30/7) - 24 = (15 • -30/7) + 6
-240/7 - 24 = -450/7 + 6 todo /•7
-240 - 168 = -450 + 42
-408 = -408
