15(4-y) = 5(10 + 2y)
60-y=60y
Are you solving for y because i don't know what to do after this step
yikes
60 - 15 y = 50 + 10 y
25 y = 10
y = 10/25
==================
check
15(4-y) = 5(10 + 2y)
15 (4 - 10/25) = 5 (10 + 20/25)
60 - 150/25 = 50 +100/25
60 - 6 = 50 + 4
54 = 54 yes it checks
i have to solve each equation...i think the answer is x = 2/5. thx
yes 10/25 = 2/5
To solve the equation 15(4-y) = 5(10 + 2y), we will use the distributive property and combine like terms. Here's the step-by-step process:
1. Distribute 15 to the terms inside the parentheses on the left side:
15 * 4 - 15 * y = 5(10 + 2y)
Simplifying the left side:
60 - 15y = 5(10 + 2y)
2. Distribute 5 to the terms inside the parentheses on the right side:
60 - 15y = 50 + 10y
Simplifying the right side:
60 - 15y = 50 + 10y
3. Combine the y terms on the right side by adding 10y to both sides:
60 - 15y + 10y = 50 + 10y + 10y
Simplifying the left side:
60 - 5y = 50 + 20y
4. Combine the constant terms on the right side by subtracting 50 from both sides:
60 - 5y - 50 = 50 + 20y - 50
Simplifying the left side:
10 - 5y = 20y
5. Rearrange the equation to isolate the variable, y:
-5y - 20y = -10
Simplifying the left side:
-25y = -10
6. Solve for y by dividing both sides of the equation by -25:
y = -10 / -25
Simplifying the right side:
y = 0.4
Therefore, the value of y that satisfies the equation 15(4-y) = 5(10 + 2y) is y = 0.4.
