Respuesta: desarrollo del problema matemático:
Here we will show you how to calculate and provide solutions to math problems related to 3x + y = 42.
We will start by calculating and showing you the solution for the x-intercept and y-intercept of 3x + y = 42.
Then, we will show you how to get the graph plot coordinates for 3x + y = 42 so we can illustrate it on a graph.
Finally, we will solve 3x + y = 42 for x and also for y, then calculate and show you the solution for the slope of 3x + y = 42.
Solution for 5x+3y=78 equation:
Simplifying
5x + 3y = 78
Solving
5x + 3y = 78
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3y' to each side of the equation.
5x + 3y + -3y = 78 + -3y
Combine like terms: 3y + -3y = 0
5x + 0 = 78 + -3y
5x = 78 + -3y
Divide each side by '5'.
x = 15.6 + -0.6y
Simplifying
x = 15.6 + -0.6y

Respuesta:
X=12 Y=6
Explicación paso a paso:
3X + Y=42
5X+3Y= 78
PRIMERO MULTIPLICO X UN NUMERO PARA SIMPLIFICAR VARIABLES EN ESTE CASO MULTIPLICARE A LA 1 ECUACION POR -3, QUEDARIA ASI:
-9X-3Y= -126
5X+3Y= 78
ENTONCES SIMPLIFICANDO DE ARRIBA PARA ABAJO Y NOS QUEDA:
-4X= -48
X= 12
REEMPLAZO X EN LA PRIMERA ECUACION PARA HALLAR Y:
3X + Y=42
3(12)+Y=42
Y=6
