Question

5(-y+4)-7(2y-1)=3(5-4y)-2(5+3y)+17

Answer 1

Resposta:

Let's solve your equation step-by-step.

5(−y+4)−7(2y−1)=3(5−4y)−2(5+3y)+17

Step 1: Simplify both sides of the equation.

5(−y+4)−7(2y−1)=3(5−4y)−2(5+3y)+17

(5)(−y)+(5)(4)+(−7)(2y)+(−7)(−1)=(3)(5)+(3)(−4y)+(−2)(5)+(−2)(3y)+17(Distribute)

−5y+20+−14y+7=15+−12y+−10+−6y+17

(−5y+−14y)+(20+7)=(−12y+−6y)+(15+−10+17)(Combine Like Terms)

−19y+27=−18y+22

−19y+27=−18y+22

Step 2: Add 18y to both sides.

−19y+27+18y=−18y+22+18y

−y+27=22

Step 3: Subtract 27 from both sides.

−y+27−27=22−27

−y=−5

Step 4: Divide both sides by -1.

−y/−1=−5/−1

y=5
