Question

9y+5=4y find the y value​

Answer 1

Answer:

9y-4y=-5

5y=-5

y=-5/5

Answer 2

Question

Find the value of 'y' in the equation ⇒ 9y+5=4y

$\rule{300}{1}$

Answer

Let's solve your equation step-by-step.

$9y + 5 = 4y$

Step 1: Subtract 4y from both sides.

$9y + 5 - 4y=4y-4y$

$5y+5=0$

Step 2: Subtract 5 from both sides.

$5y+5-5=0-5$

$5y=-5$

Step 3: Divide both sides by 5.

$\frac{5y}{5}=\frac{-5}{5}$

$y=1$

Let's verify if y = -1 step-by-step.

Method 1

$9y + 5 = 4y$

Step 1: Subtract 4y from both sides.

$9y + 5 -4y= 4y-4y$

$5y+5=0$

Step 2: Give 'y' it's value and solve.

$5y+5=0$

$5\times -1 +5$

$-5+5$

$0$

$0=0$

Method 2

$9y+5=4y$

Step 1: Give 'y' it's value and check whether LHS=RHS

$9y+5=4y$

$9\times -1 +5=4\times -1$

$-9+5=-4$

$-4=-4$

∴LHS = RHS

∴ y = -1 in the equation ⇒ 9y+5=4y
