Question

What is the solution to the system of equations ? y=5x+2 3x=-y+10

Answer 1

1,7

Explanation:

took the test

Answer 2

Solution is (1,7).

Explanation:

We need to find the solution of the system of following equations.

y= 5x + 2 eq(1)

3x = -y +10 eq(2)

We will solve the equations using Substitution method to find the values of x and y

we put value of y from eq (1) into eq (2), The eq(2) will be:

3x = - (5x + 2) + 10

3x = -5x -2 +10

3x+5x = -2+10

8x = 8

x= 1

Now, putting value of z in eq(1) to find value of y

y = 5x +2

y = 5(1) + 2

y = 5+2

y = 7

So, Solution is (1,7).
