Question

Determine whether the system of equations has one

solution, infinite solutions, or no solution:
3s =-18r + 15
12r + 2s=10
O infinite solutions
O one solution
o
O no solution

Answer 1

it has infinite solutions

Explanation:

if you simplify the 1st equation you get that s=-6r+5. you substitute that in the 2nd one and it is equal to 12r+2*(5-6r)=10. when u simplify you get 10=10
