Q. What is y+5=7(x−8) written in standard form?Choose 1 answer:(A) −7x+y=−61(B) x−7y=−61(C) 7x+y=−61(D) x+7y=−61
Distribute to both terms: First, distribute the 777 to both terms inside the parentheses.\newliney + 555 = 777(x - 888)\newliney + 555 = 777x - 565656
Subtract 555 from both sides: Next, subtract 555 from both sides to get y by itself on one side.\newliney = 777x - 565656 - 555\newliney = 777x - 616161
Move xxx-term to the same side: Now, to write the equation in standard form, Ax+By=CAx + By = CAx+By=C, we need to move the xxx-term to the same side as the yyy-term. Subtract 7x7x7x from both sides.\newline−7x+y=−61-7x + y = -61−7x+y=−61
Check the answer choices: Check the answer choices to see which one matches our equation.\newline(A) −7x+y=−61-7x + y = -61−7x+y=−61 is the correct standard form that matches our equation.
