Answer:
56 students
Step-by-step explanation:
The equation for your question is 85+2x=197. First you would have to subtract 85, on both sides, leaving you with 2x=112. Then, you'd have to divide by 2 on both sides to isolate the variable. From there, you're left with x=56.
You divide a quotient as a normal number so it would be y^3
a=6, b=2
Step-by-step explanation:
Use simplification into substitution



We can now plug this value of <em>a</em> into the second equation.
