Question

solve = y /4 -3=7 please
​

Answer 1

y/4-3=7

y/4=7+3

y/4=10

y=10×4

y=40

Answer 2

Answer :-

y = 40

Solution :-

$\sf \dfrac{y}{4} - 3 = 7$

Traspose - 3 to RHS [ - 3 becomes 3]

$\sf \dfrac{y}{4} = 7 + 3$

$\sf \dfrac{y}{4} = 10$

Transpose 4 to RHS [Division becomes multiplication]

$\sf y = 10 \times 4$

$\sf y = 40$

$\sf \therefore \: y = 40$

Verification :-

$\sf \dfrac{y}{4} - 3 = 7$

$\sf \implies \dfrac{40}{4} - 3 = 7$

$\sf \implies 10 - 3 = 7$

$\sf \implies 7 = 7$

Extra Information :-

• y/4 - 3 = 7 is a simple equation.

• These can be solved by transposing terms LHS to RHS or RHS to LHS.

• Transposing rules

1) Addition(+) becomes Subtraction(-)

2) Subtraction(-) becomes Addition (+)

3) Division becomes Multiplication

4) Multiplication becomes Division

5) Square root (√) becomes square (²)

6) Square(²) becomes square root (√)
