Hello!
To solve algebraic equations, we need to use SADMEP. SADMEP is an acronym used only solve for x in algebraic equations. SADMEP is expanded to be: subtraction, addition, division, multiplication, exponents, and parentheses.
(a) 4 + 2(-1) = 10 + 2 (multiply)
4 + -2 = 10 + 2 (add)
2 = 12
This equation has no solutions because <u>2 is never equal to 12</u>.
(b) 30 = 10 - (6 + 10) (simplify the parentheses)
30 = 10 + -1(16) (multiply)
30 = 10 - 16 (simplify)
30 = -6
This equation has no solutions because<u> 30 and -6 is never equal to each other</u>.
(c) 8x = 4x + 4x + 10(x - x)
8x = 4x + 4x + 10(x - x) (simplify [add and subtract])
8x = 8x + 10(0) (multiply)
8x = 8x
This equation has an infinite number of solutions because if you <u>substitute any value into the original equation</u>, <u>both sides of the equation</u> will be <u>always equal</u>.
Answer:
x= -2 and 9
Step-by-step explanation:
factorize it
- 18 = 2×3×3
TO MAKE IT 7
3×3=9
9-2 =7
x(x+9)-2(x+9)=0
x-2=0 ,x+9=0
x =2 x=-9
156÷13
13 goes into 15 once
so under the 156 put 13 under 15 left with 2 bring down the 6 to make it 26
13 goes into 26 2 times
so under where you wrote 26 put 26 then 26-26=0
so your answer is 12
Answer:
no
Step-by-step explanation:
because he goes backwards when he goes back home and the bus drives him home and it goes backwards.
Answer:
Hey there!
The system can be written as
l+w=20000
w+1000=l
Let me know if this helps :)
