Step: 3 and 4
In step 3 you were suppose to add 34 to both sides to cancel it out which should have given you positive 17x=40
Im kinda confused if the problem is 2(10-13)=-34x+60 were did you get 9x and 26x on the left side
Standard form: 100,000,000 (100 million)
Scientific form: 1 * 10
.
On question 7 the answer is 9x+5y+12 for question 8. The answer is7x+1 and 9. Is 12xsquared +14x and 10 is 15
