Answer:
The answer is -x+26.
Step-by-step explanation:
First you distribute the -3 into the parthensis and you get -3x+15. You write the whole expression again plus the -3x+15 you got from the distributing part so 8-3x+15+2x+3. You combine the like terms so the x with the x and the numbers with the numbers. From there you get the answer of -x+26. I hope this helps you!

Answer:
d) 40.78 inches
Step-by-step explanation:
See attached for details
4.72 x 1 = 4.72
8 x X =8x
We need to let the X alone so
4.72 divided 8 = 0.59
1 battery = 0.59
You solve for one variable like
y-5x=2
"y=5x+2"
9x+3y=58
and you plug it in into the other equation
9x+3(5x+2)=58
You solve for x and then plug in your answer for x into the other equation
*let's imagine x=8*
then:
y-5(8)=2
and solve for y

Answer:
(7,5)
Step-by-step explanation:
A system of equations is 2 or more equations for which the same x,y solution exists. We can solve the system in three ways: elimination, substitution, or graphing. Substitution can be used by substituting the value of one variable into the equation.
Because y=x-2, we can substitute x-2 into y in x+y=12.
x+(x-2)=12
x+x-2=12
2x-2=12
2x-2+2=12+2
2x=14
x=7
We now substitute x=7 into y=x-2.
y=(7)-2
y=5
