First turn the statement into an equation:
3X=12+(X+26). You can combine the 12+26 and now you should have 3X=X+38. Subtract an X from both sides of the equation (2X=38) now finally divide by 2 to find X. X=19
its 8...
3 on left, 3 on right 8 on top, 8 on bottom
Answer:
2(m-5)+6
2m-10+6
2m-4
2m-4 is equivalent to 2(m-5)+6
(4/9) divided by (7/12) = 4/9 * 12/7 = 48/63 = 16/21
