In order to solve by elimination we first need to find a common multiple of the x or y values. Lets eliminate x. 7 and 2 (both the x values) can both go into 14 without having any left over. In order to turn 7 into 14 we must multiply it by 2. But in this case, we'll multiply the entire equation by 2 in order to not change its value. 14x-4y=34 Now lets do the same for the second equation. In order to turn 2 into 14, we can multiply it by 7, but again we need to multiply the entire equation by 7 so we dont change it's value. 14x+49y=511
Now that we have the same coefficient on both the x's we can get rid of them by subtracting the two equations.
14x+49y=511 14x-4y=34
53y=477 y=9
Now that we have the value for y we can plug it in and solve for x. 7x-2(9)=17 7x-18=17 7x=35 x=5
