Solve, if possible, using the substitution method 2x + y = -10 3x – 5y = 11 What is the x-coordinate?
2x + y = -10 3x – 5y = 11; y = -2x - 10; 3x – 5(-2x - 10) = 11; 3x + 10x + 50 = 11; 13x + 50 = 11; 13x = 11 - 50; 13x = -39; x = -39/13; x = -3; 2(-3) + y = -10; -6 + y = -10; y = -10 + 6; y = -4; The x-coordinate is -3.

2x + y = -10
3x – 5y = 11;

y = -2x - 10;
3x – 5(-2x - 10) = 11;
3x + 10x + 50 = 11;
13x + 50 = 11;
13x = 11 - 50;
13x = -39;
x = -39/13;
x = -3;
2(-3) + y = -10;
-6 + y = -10;
y = -10 + 6;
y = -4;
The x-coordinate is -3.
