Question and answer
Solve the system algebraically. 4x - 5y = 3 x = 3 - y What is the value of x? 9/7 24/14 33/14
4x - 5y = 3, x = 3 - y; (x + y = 3) * (-4); -4x - 4y = -12; ( 4x - 5y = 3) + (-4x - 4y = -12); -9y = -9; y = -9/-9 = 1; 4x - 5(1) = 3; 4x - 5 = 3; 4x = 3 + 5; 4x = 8; x = 8/4 = 2; The solution set of the systems 4x - 5y = 3 x = 3 - y is {2, 1}. The value of x is 2.

Solve the system algebraically. 3x - 2y - 1 = 0 y = 5x + 4 What is the solution? {(-9/7,-17/7)} {(9/7,17/7)} {(9/7,-17/7)}
Weegy: 3x - 2y - 1 = 0 y = 5x + 4 substitute y in the first equation we get: 3x - 2(5x + 4) - 1 = 0 3x - 10x - 8 - 1 = 0 -7x = 9 x = -9/7 y = 5(-9/7) + 4 = -45/7 + 28/7 = -17/7 The solution for the system 3x - 2y - 1 = 0 y = 5x + 4 is (-9/7, -17/7) (More)
