Answer:
infinity (All real numbers are solutions)
Step-by-step explanation:
4x +2x -12 = 6x -12
6 x = 6x
6x - 6x =0
Answer:
x = 45
Step-by-step explanation:
5 (2x - 5) = 1/2 (18x + 40)
10x - 25 = 9x + 20
10x = 9x + 45
x = 45
First we have to make the fractions even so there denominator have to be equal. So 15 times 2 gets 30 and 6 times 5 gets 30 too. Ok now multiply the nominator by the corresponding number of 25/30 and 16/30. Subtract to get 9/30 now simplify to get 3/10.
