Find the solution to the system of equations: x + 3y = 7 and 2x + 4y = 81. isolate x in the first equation:2. substitute the val

disa [49]

Simultaneous equations:
x+3y = 7 ---- (1)
2x+4y = 81 --- (2)

From eqn (1)
x = 7-3y ---- (3)
Substituting for x in eqn (2)

2(7-3y)+4y = 81
14-6y+4y = 81
14-2y = 81
-2y = 81 - 14 = 67
-2y = 67
y = 67/-2 = -33.5

And then, from eqn (3);
x = 7-3y = 7-3(-33.5) = 7-100.5 = -93.5

The solution for the system of equations is;
x = -93.5
y = -33.5
