Simplify.7x + 3y - 2 + 6x + 1 + y squared 2 you! ; )

50 will mark show all use the linear combination method to solve the system of equations. explain each step of your solution. if steps are not explained, you will not receive credit for that step. 2x+9y= -26 -3x-7y=13

If a=0.333333 and b=0.55555, what is the value of a+b
