Question

I need help writing algebraic expressions into equations

1) the product of a number and 7 is 63
2) 10 subtracted from a number is 15
3) two-fifths of a number is -12
4) 8% of a number is 20
5) the sum of twice a number and 17 is -1
6) nine less than the product of a number and -4 is 35
7) seven more than the quotient of a number and 3 equals 11
8) the difference between half a number and 11 is -25

Answer 1

"of" means multiply
"product of a and b" means a*b
and so on. So,
#5, 2x+17 = -1
