Question

Solve for y: -3x + 4y = 28

Answer 1

Hello!

Answer:

`\Large \boxed{\sf y = 7 + 0.75x}`

Explanation:

→ We want to solve y in this equation:

`\sf -3x + 4y = 28`

◼ Add 3x to both sides:

`\sf -3x + 4y +3x= 28+3x`

◼ Simplify both sides:

`\sf 4y = 28+3x`

◼ Divide both sides by 4:

`\sf (4y)/(4) = (28+3x)/(4)`

◼ Simplify both sides:

`\boxed{\sf y = 7 + 0.75x}`

Conclusion:

In the equation -3x + 4y = 28, y is equal to 7 + 0.75x.
