-2x-5y=49 ; 4x+3y=35 /using elimination method/ SHOW WORK
To do the elimination method, line the two equations up and add them together.
-2x - 5y = 49
4x + 3y = 35
We could add them together now, but it won't help us find the value of x or y . So multiply the first equation through by 2 .
-4x - 10y = 98
Now line this up with the second equation and add them together.
-4x - 10y = 98
4x + 3y = 35
0 - 7y = 133
-7y = 133 Divide both sides of this equation by -7 .
y = -19
Plug this value for y into either equation to find the value of x .
-2x - 5(-19) = 49
-2x + 95 = 49 Subtract 95 from both sides of this equation.
-2x = -46 Divide both sides of this equation by -2 .
x = 23
