A) find the angle marked f. justify.
(4x - 2)
(3x + 7)"

Solve the given system of equations. 2y= -x+9 , 3x-6= -15

If sr is 4.5cm and tr is 3cm, what is the measure in degrees of angle s?

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
