If you are trying to eliminate the y, then both of the numbers in front of the y have to be the same, but one needs to be negative and the other positive.
The easiest way to do this is multiply the top equation by 3, so you'd get -6y for the top and you could cancel it out with the +6y on the bottom.
D. Multiply the top equation by 3.

2π is the period of `y = 1+ tan((1)/(2)x)`
Let's solve your equation step-by-step.
2(x+4)=−5x+1
Step 1: Simplify both sides of the equation.
2(x+4)=−5x+1
(2)(x)+(2)(4)=−5x+1(Distribute)
2x+8=−5x+1
Step 2: Add 5x to both sides.
2x+8+5x=−5x+1+5x
7x+8=1
Step 3: Subtract 8 from both sides.
7x+8−8=1−8
7x=−7
Step 4: Divide both sides by 7.
7x
