Solve the system of equations by substitution. What is the solution for x? (1 point)
Cerrena [4.2K]
                 2x + y = 1
          2x - 2x + y = 1 - 2x
                         y = 1 - 2x
                         y = -2x + 1
               4x + 2y = -1
    4x + 2(-2x + 1) = -1
4x + 2(-2x) + 2(1) = -1
          4x - 4x + 2 = -1
                         2 ≠ -1

The solution of the problem can't be a solution because they are both parallel lines, which means they have no solution.

A group of students went on a field trip. There were 3 boys for every 4 girls in the group. If there were 20 girls, how many stu
guajiro [1.7K]

Answer:

35 students

Step-by-step explanation:

So if every 3 boys there is 4 girls you can solve that there is 5 times the amount of girls to get to 20. So to solve for the boys you do the same.

3 x 5 = 15

That means there are 15 boys and 20 girls but we want to know the total so what you do is just add 15+20=35

So 35 total students.

Hope that helps and have a great day!
