Answer:
see below!!
Step-by-step explanation:
x + 3y = 5,
y = –x + 3
Substitute the point into each equation and verify that it is true
x + 3y = 5, 2 +3(1) = 5 5 = 5 true
y = -x +3 1 = -2+3 1=1 true
(2,1) is a solution
Answer:
y-6x=-27
Step-by-step explanation:
simplify with distributive property
y-3=6x-30
add 3 to both sides
y=6x-27
take away 6x from both sides
y-6x=-27

Responder:
x = 42,4
Explicación paso a paso:
Podemos encontrar el valor de x ya que no se nos dice qué buscar
La suma de dos ángulos suplementarios es 180 grados, por lo tanto;
2x - 14 + 3x - 18 = 180
2x + 3x - 32 = 180
5 veces = 180 + 32
5 veces = 212
x = 212/5
x = 42,4
Por tanto, el valor de x es 42,4
