u= 32 - 6y
u = 17 - 3y

Step 1
32 - 6y = 17 - 3y

Step 2
-6y + 3y = 17 - 32

Step 3
-3y = - 15

Step 4
3y = 15

Step 5
y = 15/3

Step 6
y = 5

U+6y=32
U+3y=17

Solve U+6y=32 for u


Add -6y to both sides


U+6y-6y=32-6y
U= -6y+32


Substitute -6y+32 for U in U+3y=17
U+3y=17
-6y+32+3y=17

Simplify both sides of the equation
-3y+32=17

Add -32 to both sides
-3y+32-32=17-32
-3y=-15


Divide both sides by -3
-3y/-3 = -15/-3
Y=5


Substitute 5 for y in U=-6y+32
U= -6y+32


U= (-6)(5)+32
u= -30 +32
U= 2

Answer : U= 2 and Y=5

I hope that's help and have a great night !
