Solving systems of equations using substitution  By: Gilberto Suarez
Y = 5x +11 y=10x - 4
Y = 5x +11 y=10x - 4  5x+11=10x-4
Y = 5x +11 y=10x - 4  5x+11=10x-4 -5x  -5x  11 =5x -4  +4=  +4 15=  5x  5  5 3=x
Y = 5x +11  5(3)+11=26 y=10x – 4  10(3)-4=26  5x+11=10x-4  -5x  -5x  11 =5x -4  +4=  +4  15=  5x  5  5  3=x
Y = 5x +11  5(3)+11=26 y=10x – 4  10(3)-4=26  5x+11=10x-4  -5x  -5x  11 =5x -4  +4=  +4  15=  5x  5  5  SOLUTION  3=x  (3,26)
