I think it's a pattern, so x would be 3 and y would be 5 for the first one
x would be 20 for the second
and i dont even do word problems so...
<span>y = −2x + 13
y = 2x − 3
</span>−2x + 13 = 2x − 3
subtract 2x on both sides
−2x + 13 −2x = 2x − 3 - 2x
simplify
-4x + 13 = -3
subtract 13 on both sides
-4x + 13 -13 = -3 - 13
simplify
-4x = -16
divide both sides by (-4)
x = 4
substitute x = 4 into y = 2x − 3 to find y
y = 2x − 3
y = 2(4)− 3
y = 8 - 3
y = 3
answer
solution x = 4 and y = 3
hope it helps
Then it holds 8 gallons.
Comment the rest of the answer if you want. Thanks!
Answer:
see the procedure
Step-by-step explanation:
we have
step 1
Let
y=f(x)
step 2
Exchange the variables
x for y and y for x
step 3
Isolate the variable y
step 4
Let
Answer:
x=8
Step-by-step explanation:
2.25x=1.5x+6
-1.5x -1.5x
0.75x=6
3/4x=6
x=6*4/3
x=24/3
x=8
