Divide both sides by f then cancel out
Answer:
w= 9 3/4
Step-by-step explanation:
4 1/5 =21/5
13 19/20= 279/20
w+21/5 + 279/20
-21/5 -21/5
w+39/4
w=9 3/4
Answer:
(1, 2 )
Step-by-step explanation:
x + y = 3 (subtract x from both sides )
y = 3 - x → (1)
2x - y = 0 → (2)
Substitute y = 3 - x into (2)
2x - (3 - x) = 0
2x - 3 + x = 0
3x - 3 = 0 ( add 3 to both sides )
3x = 3 ( divide both sides by 3 )
x = 1
Substitute x = 1 into (1)
y = 3 - 1 = 2
solution is (1, 2 )
