Solve the system by substitution. y = 4x + 3 y = 72

Mathematics
1 answer:
Sever21 [200]4 years ago
4 0

Answer:

17.25

Step-by-step explanation:

You already know y = 72, so you could rewrite the equation to 72 = 4x + 3. To get to the answer, you need to find what X is. What you should do is subtract 3 from both sides, get 69, divide by 4 on both sides and get 17.25

I'm not sure if this is correct, but I hope this helped.

(2.01) solve -2(2x + 5) - 3 = -3(x - 1)
steposvetlana [31]
<span>solve -2(2x + 5) - 3 = -3(x - 1)

-4x - 10 -3  = -3x + 3
-4x - 13 = -3x + 3

Add 3x to both sides
-4x - 13 +3x = -3x +3

Simplify
-x - 13 = 3
Add 13 to both sides
-x - 13 + 13 = 3 + 13

Simplify 
-x = 16

multiply both sides by (-1) 
x = -16</span>

Answer:

Hello! answer: y = 40 x = 67

Step-by-step explanation:

63 - 23 = 40 therefore y = 40
