x+3(x-5)=9 Substitute y=x-5 into every y into the first equation and solve for x
x+3x-15=9
4x=24
x=6
Substitute x into any equation and then solve for y.
y=(6)-5=1
x=6, y=1
Hope that helps!
Answer:
102 cm
Step-by-step explanation:
P = how many cars Peter has
j = how many cars Jade has
a = how many cars Andre has
p x 4 = how many cars Andre has (36 model cars)
>>>TO FIND HOW MANY MODEL CARS PETER HAS:
p x 4 = 36
36 / 4 = 9
your equation to find how many model cars Peter has is:
36 / 4 = 9
So, Peter has 9 model cars.
>>>TO FIND HOW MANY MODEL CARS JADE HAS:
36 / 4 = how many cars Peter has (9)
Now, you are given the info that Jade has THREE TIMES (3x) as many cars as Peter already.
So, your equation for this one is:
9 x 3 = 27
So Jade has 27 model cars.
---- Jade has 27 model cars.
---- Andre has 36 model cars.
---- Peter has 9 model cars.
equation for a. 36 / 4 = p
equation for b. 9 x 3 = j
Y=1/2x-3 (simplified from y=2/4x-3)
Hope this helps
Solve the equation
Add 9t to both sides
0 = -1, false
The answer is no solution
