Answer: (1,2)Step-by-step explanation: You must: - Multiply the first equation by 3. - Add both equations. - Solve for the variable left. In this case will be x. Then: [tex]\left \{ {{39x +3y = 45} \atop {-9x - 3y = -15}} \right.\\------\\ 30x=30\\x=1[/tex] Substitute x=1 into any of the original equtions and solve for y: [tex]13(1)+y=15\\y=2[/tex] The solution is: (1,2)
