It’s 17/20 because it just is
You would have to do distribution. So you would have to multiply 3 by 2a and multiply 3 by -8b. 3 times 2a equals 6a (always keep the letter) and 3 times -8b equals -24b. (if there is only one negative number when multiplying, always keep the negative sign.) now you are left with 6a-24b. and since we cant put a into b, your answer would be 6a-24b. hopefully this helped you and sorry if it confused you
1) x + 3.2= -3.5
subtract 3.2 from both sides
x+ 3.2 - 3.2= -3.5 - 3.2
it cancels out on the left
x= -6.7
2) 8/9x= 32
divide both sides by 8/9
8/9x ÷ 8/9= 32 ÷ 8/9
it cancels out on the left
to divide on the right, multiply fraction by its reciprocal/inverse
x= 32 * 9/8
multiply numerators (top)
x= (32*9)/8
x= 288/8
x= 36
ANSWER: 1) x= -6.7; 2) x= 36
Hope this helps! :)
