Answer:
-4
Step-by-step explanation:
Given the expression 2(-2x-4)+6=5-3(x+1), we are to find the value of x that will make the expression true:
2(-2x-4)+6=5-3(x+1)
Open the parenthesis
2(-2x)-2(4)+6 = 5-3(x)-3
-4x-8+6 = 5-3x-3
Collect like terms
-4x-2 = -3x+2
Collect like terms
-4x+3x = 2+2
-x = 4
Divide both sides by -1
-x/-1 = 4/-1
x = -4
Hence the value of x that makes the equation true is -4
7/50 is in its simplest form because 7 is a prime number and it is not divisible by any number except 7 or 1
Answer:
idk the answer but here is the explanation but the answer should be 78=13
Step-by-step explanation:
Simplifying
(13) * 2(13) + -4(13) * 5 = 13
Multiply 13 * 2
26 * 13 + -4(13) * 5 = 13
Multiply 26 * 13
338 + -4(13) * 5 = 13
Multiply -4 * 13
338 + -52 * 5 = 13
Multiply -52 * 5
338 + -260 = 13
Combine like terms: 338 + -260 = 78
78 = 13
Solving
78 = 13
(x + 1) / 5 = (x + 5) / 7
cross multiply
(x +1) x 7 = 5 x (x + 5)
7x + 7 = 5x + 25
take the like terms to one side
7x - 5x = 25 - 7
2x = 18
divide by 2 to isolate x
2x / 2 = 18 / 2
x = 9
check:
9 + 1 / 5 = 9 + 5 / 7
10 / 5 = 14 / 7
2 = 2
