2x + 3y = 6

x + 2y = 5

Just substitute for x and y then you get the answers

a. 6

b. 5

Answer: y = 4, x = - 3. You have to multiply one of the equations to get a common multiple for x, so multiply the second equation by 2 to get both of the x's as 2x. Then, you will subtract the two equations and solve for y. You should get - 1y = - 4, and solving for y will give you y = 4. Plug in y to get x, and you should get x = - 3. So the answer is y = 4, and x = - 3.
