What is 3(x+1)=5(x-2)+7

Mathematics
1 answer:
Yuliya22 [10]3 years ago

Distribute 3 to all terms within the parenthesis

3(x + 1) = 3x + 3

Distribute 5 to all terms within the parenthesis

5(x - 2) = 5x - 10

3x + 3 = 5x - 10 + 7

Simplify

3x + 3 = 5x (-10 + 7)

3x + 3 = 5x - 3

Isolate the x. Subtract 3 from both sides and 5x from both sides

3x (-5x) + 3 (-3) = 5x (-5x) - 3 (-3)

3x - 5x = -3 - 3

Simplify

-2x = -6

Isolate the x. Divide -2 from both sides

-2x/-2 = -6/-2

x = -6/-2

x = 3

3 is your answer for x.

hope this helps

How do you get 25% of what number is 21
STatiana [176]
<span>So the question is 25% of what number is 21. Lets turn that into an equation: let x be the number we are looking for. We need to take 25% from it and we know that that is equal to 21. Mathematically: 25% * x= 21. Or: (25/100) * x = 21. When we multiply both sides with 100 and divide both sides by 25 we get: x=21*(100/25). And we get that x=84. </span>
