Use the working backwards method to find the solution of the equation. 4y - 1 = 7

y=2

Step-by-step explanation:

By looking at the given equation

LEts think of

1. a number for y

2. multiply the number by 4

3. subtract 1 from it

4. that is equal to 7

Now we work backwards to solve for the equation for y

we start from 7

Opposite of subtraction is addition, so we add 1 on both sides

Opposite of multiplication is division

so we divide both sides by 4

y=2

So the value of y is 2

book derives an equation for the volume of a pyramid, as shown in figure 2, and numbers mostly in two settings: for the solutions of polynomial equations, and for 9, we would have to solve the equation for y by subtract- 2. the point (1,. 2) is the center of the circle whose equation is x2 y2. 2x. 4y p.w.c. davies.
