Answer: y = 7.5
Step-by-step explanation: To solve for <em>y</em> in this equation, we want to get <em>y</em> by itself on the left side of the equation.
Since <em>y</em> is being multiplied by 4, to get <em>y</em> by itself, we need to divide by 4 on the left side of the equation. Since we divided by 4 on the left side, we must also divide by 4 on the right side.
On the left side, the 4's cancel out so we're simply left with <em>y</em>. On the right side, we have 30 divided 4 which is 7.5.
So we have <em>y = 7.5</em>.
