You can solve for the variable by using cross products.
4.4
To solve the proportion, we will start by using cross products. Remember that we will need to treat y+1 as a single quantity in the cross multiplication process.
We will continue solving for y using the Distributive Property and the Properties of Equality.
Distribute 5
LHS-5=RHS-5
.LHS /5.=.RHS /5.
Rearrange equation
When y=4.4, the ratios are proportional.
