-30= 5 (x+1 )
-5 from 5= 0
-5 from -30= -35
-35= (x+1)
1/-35= -35
Answer:
57
Step-by-step explanation:
Answer: 6x + 8y =1,245
Step-by-step explanation:
Hi, to answer this question we have to write an equation for each person:
Jack = The total cost (650) must be equal to the product of the number of shirts he bought (2) and the price per shirt (x); plus the product of the number of pair of jeans he bought (5) and the price per jean (y).
2 x+ 5 y=650
Dylan = The total cost (595) must be equal to the product of the number of shirts he bought (4) and the price per shirt (x); plus the product of the number of pair of jeans he bought (3) and the price per jean (y).
4x+3y = 595
Vertical addition:
2 x+ 5 y=650
+
4x+3y = 595
_________
6x + 8y =1,245
Answer:
A
Step-by-step explanation:
The correct answer to this problem is letter A.
Answer: Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
4*x+2*x+1-(2*x-x+21)=0
Step by step solution :
STEP
1
:
Pulling out like terms
1.1 Pull out like factors :
5x - 20 = 5 • (x - 4)
Equation at the end of step

STEP
2
:
Equations which are never true:
2.1 Solve : 5 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation:
2.2 Solve : x-4 = 0
Add 4 to both sides of the equation :
x = 4
One solution was found :
x = 4
