Match the following items. am i right 1. 2x + x + 4 = -17 2 combine like terms 2. 3x + 4 = -17 3 subtraction 3. 3x = -21 4 division 4. x = -7 1 given

Yup correct :D
thrs a shorter method though

Imagine +4 flying over the = sign, and just change the sign (from + to -)
It is a lot shorter, as long as you can visualise. If for example -10 is flying over, it becomes +10

student B is correct

Step-by-step explanation:

we know that 5 dollars will be donated for every 10 tickets sold. so we know that y is dollars donated so if we plug it in, we have 5 =_x . and we know that x represents tickets sold so 10 tickets are sold for 5 dollars donated so now we have 5 = _×10 and now we just fill in the blank, 1/2 times 10 equals 5 so student b is correct
