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:
-5x - 6y + 8
Step-by-step explanation:
-2(x - 4) -3(x + 2y)
-2x + 8 - 3x - 6y
-5x - 6y + 8
Hope this helps!
Answer:
76(10) + (-114)10 = (-38)10
Step-by-step explanation:
To express -114 in two complement
First convert to binary = 0000 0000 0000 0000 0000 0000 0111 0010
Change 1 to 0 and o to 1 = 1111 1111 1111 1111 1111 1111 1000 1101
add 1 to = 1111 1111 1111 1111 1111 1111 1000 1110
(76)10 complement = 0000 0000 0000 0000 0000 0000 0100 1100
Adding the two = 1111 1111 1111 1111 1111 1111 1101 1010 (-38)
0(10) in 16 -bit binary =
0000 0000 0000 0000
