2)3t +16t-48=2+14t…put like terms together, 19t-48=2+14t…get t by itself, subtract 14t from both sides…5t-48=2…add 48 to both sides, 5t=50, divide to get t…t=10

3)2v+18=16-4v-28…like terms, 2v+18=-4v-12…add 4v to both sides, 6v+18=-12…subtract 18 from both sides, 6v= -30, divide by 6…v= -5

4)4x-9+3x=8x-1 (don’t forget there is a 1 after the negative in front of the parenthesis and a neg times a neg is a positive)…like terms, 7x-9=8x-1, get x alone, subtract 7x from both sides…-9=x-1 add 1 to both sides, x=10

5) -7+28m=26m-39, subtract 26m…-7+2m=-39, add 7 to both sides, 2m= -32, divide by 2…m= -16

6) 4x+35x-15=9x-45…like terms, 39x-15=9x-45, subtract 9x…30x-15= -45, add 15 to both sides…30x= -30, divide by 30…x= -1

7)32u-8-12u=22u-66…like terms, 20u-8=22u-66, subtract 20u…-8=2u-66, add 66…58=2u, divide by 2…u=29

Hope I was helpful…good luck!
