3x = 24-24y
x = 8-8y
Substitute 8-8y for x in second equation (above) and solve for y. Insert that value into the first equation and solve for x. Check by inserting both values into the second equation.
using the substitution method. Show your work. If the system has no solution or an infinite number of solutions, state this.
3x + 24y = 24
27x – 15y = -15
