Question

Use substitution to solve each system of equations. Check your solution.

x − 5y = 2
9x + 8 = 15y

Answer 1

so you should get one of equation for x or either for y

Answer 2

so i would recommend first one is easy to solve for x so we can substitution in another equation

Answer 3

can you solve first equation for x ??

Answer 4

9x+8 = 15 (5y + 2) ??

Answer 5

not quite.

if you add 5y to both sides in the first equation, you get
x=2+5y
