I need help finding out why they are congruent

Advocard [28]

Ok so if 5x + 24 equals 9x - 17, the we can write it like this:

5x + 24 = 9x - 17 ~~~ We have to get x on one side to find out what it is. So you can either subtract 5x from both sides or 9x from both sides. Imma subtract 5x from north sides which becomes:

5x - 5x + 24 = 9x - 5x - 17 Now simplify

24 = 4x - 17 Now isolate 4x. To do that we have to add 17 to both sides

24 + 17 = 4x - 17 + 17 Now simplify

41 = 4x Now we have to get x alone on one side. So divide 4 from both sides. Becomes

41/4 = 4x/4 Now simplify.

Is 1/8 - 10× (3/4-3/8X) + 5/8X equivalent to -1/8 × (59-35X)

zubka84 [21]

Yes, Both are equivalent.

<u>Step-by-step explanation:</u>

Step 1:

To find the equality between the given terms Use the BODMAS (Brackets Orders Division Multiplication Addition Subtraction)

RHS SIDE:

$(1/8)-10*((3/4)-(3/8*X)+(5/8*X)$

Equation after 1st modification

$(1/8)-((15/2)-(15/4*X))+(5/8*X)$

Equation after Second modification

$((1/8)-(15/2)+(15/4*X)+(5/8*X))$

Equation after Third modification

LCM 2,4,8 is 8

And taking LCM equation changes to $(1-60+30*X+5*X)/8$

Equation after Final modification

$(-59+35*X)/8$ --------- 1

Step 2:

LHS SIDE:

$-1/8*(59-35X)$

By applying the BODMAS rule in the above equation we will get

$(-59+35*X)/8$ ------------ 2

From equations 1 & 2, the expression $(1/8)-(10*((3/4)-(3/8*X))+(5/8*X)$ is equivalent to $(-1/8)*(59-35*X)$
