Answer:

x = 70 y = 26

Step-by-step explanation:

well if you take 70 x 3, you get 210 + 26 is 236.

if you take 70 x 2 you get 140. then you take 140 + (3 x 26) and you get 218. trust me

I dont know how to do this
Kipish [7]
So what you're going to do is just multiply how you were normal to play multiply the numerator times the other numerator then multiply the denominator's and that should get you your answer and then you can try and simplify it by finding if it can be divided equally then see if it is bigger or smaller

SOLVE FOR X??? <br><br><img src="https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B3%7D%20%2B2%20%3D%5Cfrac%7Bx%7D%7B4%7D%2B3" id="TexFor
natima [27]

Answer:

\boxed{ \bold{ \boxed{ \sf{1. \:  \:  \:  \:  \: x = 12}}}}

\boxed{ \bold{ \boxed{ \sf{2. \:  \:  \:  \:  \: x = 3}}}}

Step-by-step explanation:

\sf{1. \:  \:  \:  \:  \frac{x}{3}  + 2 =  \frac{x}{4}  + 3}

Move x / 4 to left hand side and change its sign

Similarly, move 2 to right hand side and change it's sign

\longrightarrow{ \sf{ \frac{x}{3}  -  \frac{x}{4}  = 3 - 2}}

Take the L.C.M of 3 and 4

L.C.M of 3 and 4 = 12

\longrightarrow{ \sf{ \frac{x \times 4 - x \times 3}{12}  = 3 - 2}}

\longrightarrow{ \sf{ \frac{4x - 3x}{12}  = 3 - 2}}

\longrightarrow{ \sf{ \frac{x}{12}  = 3 - 2}}

Subtract 2 from 3

\longrightarrow{ \sf{ \frac{x}{12}  = 1}}

Do cross multiplication

\longrightarrow{ \sf{x  = 1 \times 12}}

\longrightarrow { \sf{x = 12}}

--------------------------------------------------------------------

\sf{2. \:  \:  \:  \: 3(4 + 2x) = 33 - x }

Distribute 3 through the parentheses

\longrightarrow{ \sf{12 + 6x = 33 - x}}

Move x to left hand side and change it's sign

Similarly, move 12 to right hand side and change it's sign

\longrightarrow{ \sf{6x +  x = 33 - 12}}

Collect like terms

\longrightarrow{ \sf{7x = 33 - 12}}

Subtract 12 from 33

\longrightarrow{ \sf{7x = 21}}

Divide both sides by 7

\longrightarrow{ \sf{ \frac{7x}{7}  =  \frac{21}{7} }}

Calculate

\longrightarrow{ \sf{x = 3}}

Hope I helped!

Best regards! :D
