______________
5
Cross Multiply
___________
3 + 19 + 8 + 32 + = 15 x 5
x + 62 = 75
Subtract 62 from both sides of the equation to isolate x:

A. (1.34)(5.46) = (1.76)(x)

Alja [10]

We are given an equation with an unknown variable x. We can find the value of x by dividing both sides by 1.76, as this will leave only x on the right hand side of the equation and its value on the left hand side, as shown below:

$(1.34)(5.46)=1.76(x) \\ \\ 
 \frac{(1.34)(5.46)}{1.76} = \frac{1.76(x)}{1.76} \\ \\ 
 \frac{(1.34)(5.46)}{1.76} =x \\ \\ 
4.16=x$

Thus solving the given equation, we get x =4.16, rounded of to nearest hundredth.
