Step-by-step explanation:
Explanation:
solving the first equation for x:
substracting 3y
2x=1+3y
dividing by 2 we get
x=12+32y
plugging this in the second equation
5(12+32y)+4y=14
multiplying by 2
5(1+3y)+8y=28
5+15y+8y=28
collecting like Terms
23y+5=28
substracting 5 and dividing by 23
y=1
so we get
