is (-2, 2) a solution to this system of equations?\n5x + 3y = -4\n3x - 2y = -10\nyes\nno
Answer
Explanation:
Step1: Substitute into first - equation
Substitute (x=-2) and (y = 2) into (5x + 3y). [5\times(-2)+3\times2=-10 + 6=-4] The left - hand side equals the right - hand side of the first equation.
Step2: Substitute into second - equation
Substitute (x=-2) and (y = 2) into (3x-2y). [3\times(-2)-2\times2=-6-4=-10] The left - hand side equals the right - hand side of the second equation.
Answer:
yes
