Seven more than 3 times a number is equal to 49 can be put into an equation form, which would be 7 + 3x = 49. With this equation we can work it out, first we will subtract 7 from both sides of the equation to cancel out the 7. 49 - 7 = 42. Now we have 3x = 42. To isolate x and give us the answer we will divide by 3 on both sides, since 3 is being multiplied by x. This will give us our answer, which is 14.
1. 2x²-3x²-3x+5x+1-2=-x²+2x-1
2.3x²+5x-2x+6-1=3x²+3x+5
3.-7n²-5n²+4n+6n+3+1=-13n²+10n+4
I think these are the answers if not I'm sorry
