Answer 2

[1] 3x/8 + y/3 = 17/24
[2] x + 7y = 8
To remove fractions, multiply equations by their respective LCD

Multiply equation [1] by 24


Equations now take the shape:

[1] 9x + 8y = 17
[2] x + 7y = 8


Solve equation [2] for the variable x

[2] x = -7y + 8

Plug this in for variable x in equation [1]

[1] 9•(-7y+8) + 8y = 17
[1] - 55y = -55
Solve equation [1] for the variable y


[1] 55y = 55

[1] y = 1
By now we know this much :

x = -7y+8
y = 1
Use the y value to solve for x

x = -7(1)+8 = 1

solution {x,y} = {1,1}
