Question

Use the method of substitution to solve the system of linear equations.
4a = 2 - b
4a = 6 - b

Answer 1

if you need to use substitution, even though its longer than elimation... you need to take the first equation and solve for b.
so b=-4a+2, then substitute into the second and get
4a=6+4a-2, solve and you get 0=4, which is inconsistent... so there is no solution

Answer 2

those two lines are parallel, they never touch, so there is no solution, you could graph as well and see.

Answer 3

thanks... i solved the equations wrong.. thanks for all your help
