I think the answer's a 20/6. Hope this helps
4x + 6
3x - 2 = x + 8
x = 5
MF = 26
Answer:
sure. x=12
Step-by-step explanation:
firstly! we know that the two sections equal 90 degrees (because a right angle is 90 degrees). so, take both of those sections, and put them equal to 90 in an equation.
it would look like this...
(x+42) + (3x) = 90
which is the same as...
<u>x + 42</u> + <u>3x</u> = 90. ignore the parenthesis. they're just for clarification. then we will solve for x!
add similar things together! see x and 3x? those are similar because they have x in them. (HOWEVER! if it's something like x² and x, do not add them together!) x is the same as 1x, by the way. so 1x + 3x. ignore the Xs and add the numbers. it becomes 4x
4x + 42 = 90
move 42 to the other side by minusing it on both parts of the equation!
4x = 90 - 42
4x = 48
divide 48 by 4 so x is alone. there ya go
