For what value of y is true that: 7(y+4)-3(y-5)=6y+35
Multiply the 7 by the term in parenthesis 7(y+4)=7y+28. Now multiply the -3 by the term in parenthesis so you have 3(y-5)=-3y+15. Now on the left side of the equation you have 7y+28-3y+15. Combine like terms so that 7y-3y=4y and 28+15=43. The left side of the equation now simplifies to 4y+43=6y+35. Subtract the 4y on both sides and 35 on both sides. The equation reads 2y=8. Divide both sides by 2 to get the answer, y=4.
