Answer:
Step-by-step explanation:
11x = 44
X=4
44 + 7 = 51
5x = 20
31 + 20 =51
51 = 51
Step-by-step explanation:
5m³ + 2m - 7m³ - 8m
= -2m³ -6m
= -2m(m² + 3)
Ok so right now leave the x's alone. Now add/subtract the numbers without variables which would equal to 0 since -1+4 = 3 and 3-3 =0
now 7x+x =8x so 8x is answer
