Question

that means that their measures sum to 69°. use the relationship you determined to write an equation to help you solve for x. view solution history 16x - 3 = 69 16x = 69 + 3 multiply both sides : multiply both sides by what? 16x(□) = 72(□)

Explanation:

Step1: Recall solving linear equations

To solve \(16x = 72\) (since \(16x=69 + 3=72\)), we need to isolate \(x\). We do this by multiplying both sides by the reciprocal of \(16\), which is \(\frac{1}{16}\).

Step2: Apply the multiplication

Multiply both sides of \(16x = 72\) by \(\frac{1}{16}\). So we have \(16x\times\frac{1}{16}=72\times\frac{1}{16}\).

Answer:

The value to multiply both sides by is \(\frac{1}{16}\) for both boxes. So the equation becomes \(16x\times\boldsymbol{\frac{1}{16}} = 72\times\boldsymbol{\frac{1}{16}}\) (and then simplifying would give \(x=\frac{72}{16}=\frac{9}{2}\) but the question is just about what to multiply both sides by).
