Answer:
first one is -1, second one is also -1, third one is -1/2, the fourth one is 9/4, the fifth one is 2, and the last one (sixth) is 16/25.
Step-by-step explanation:
4x +3 = -1 all multiply by 13, = 4x + 3 = -1, subtract 3 on both sides, x= -1. Do what I told you the first equation and you will get it. put all the denominators in common denominator which in this case is 6, then multiply everything by 6, add like terms, = -2x + 2 = 3, then subtract 2 on both sides, then divide -2 on both sides. put all denominators to 16 then multiply everything by 16, 4x -6 will = to 3, add 6 on both sides, 4x = 9, then divide 4 on both sides then you will get 9/4. put all of the denominators up to 12, and multiply everything by 12, then add like terms, 7 = 2x +3, subtract 3 on both sides, 4 = 2x, divide 2 on both sides now, and the answer is 2. the last one is also pretty simple, put all the denominators to 21, multiply everything by 21, add like terms, 16x = 25, divide 16 on both sides, then the answer is 16/25.
