Answer 1

$\Large{\bf{\green{\mathfrak{\dag{\underline{\underline{Given:-}}}}}}}$

• 5y - 1 = 3y + 4 and 7 (x + 4) = 2x - 7

$\Large{\bf{\orange{\mathfrak{\dag{\underline{\underline{To \: Find:-}}}}}}}$

• Values of x and y.

$\Large{\bf{\red{\mathfrak{\dag{\underline{\underline{Solution:-}}}}}}}$

First,

• 5y - 1 = 3y + 4

• 5y - 3y - 1 = 4

• 2y - 1 = 4

• 2y = 4 + 1

• 2y = 5

• y = $\sf \dfrac{5}{2}$

Second,

• 7 (x + 4) = 2x - 7

• 7x + 28 = 2x - 7

• 7x - 2x + 28 = - 7

• 5x + 28 = - 7

• 5x = - 28 - 7

• 5x = - 35

• x = $\sf \dfrac{- \: 35}{5}$

• x = - 7

Therefore,

• $\boxed{\purple{\textsf{Value of x = - 7.}}}$

• $\boxed{\blue{\sf{Value\: of\: y \:=\: \dfrac{5}{2}}}}$

$\Large{\bf{\pink{\mathfrak{\dag{\underline{\underline{Logic:-}}}}}}}$

• Here, we have to just transpose all the variables to one side and the numericals to another side and solve it.

• If the variable is enclosed within the brackets, then you have to multiple it with the number/variable out the brackets and solve for the variable.
