Question

3x+4y=34 . In the equation, what is the y-value when x=10? x= 10 , y= ?

Answer 1

y = 1

Explanation:

3x + 4y = 34 x = 10

3(10) + 4y = 34

30 + 4y = 34

4y = 4

y = 1

So, the y-value is 1 when x = 10

Answer 2

`\huge\text{Hey there!}`

`\mathsf{3x + 4y = 34}`

`\mathsf{3(10) + 4y = 34}`

`\mathsf{30 + 4y = 34}`

`\mathsf{4y + 30 = 34}`

`\large\text{SUBTRACT 30 to BOTH SIDES}`

`\mathsf{4y + 30 - 30 = 34 - 30}`

`\large\text{SIMPLIFY IT!}`

`\mathsf{4y = 34 - 30}`

`\mathsf{4y = 4 }`

`\large\text{DIVIDE 4 to BOTH SIDES}`

`\mathsf{(4y)/(4) = (4)/(4)}`

`\large\text{SIMPLIFY IT!}`

`\mathsf{y = (4)/(4)}`

`\mathsf{y = 1}`

`\huge\text{Therefore your answer should most likely be:}`

`\huge\boxed{\mathsf{y = 1}}\huge\checkmark`
