(2y+3)-(4y+7)/2y-4=5/1
Answers
Answer:
y = -1/5
Step-by-step explanation:
(2y + 3) - (4y + 7) /2 -4 = 5/1
Open the second bracket by multiplying the negative sign
2y + 3 - 4y - 7 /2y -4 = 5
Denominator of 5 is 1 so it holds no value. Move the negative 4 on other side of the equals to sign and it would become positive
2y + 3 - 4y - 7 /2y = 5 + 4
Subtract 2y from -4y and apply the sign of bigger coefficient. Add 5 and 4.
-2y - 4 /2y = 9
Shift the denominator on the other side of equals to sign and it will be multiplied with 9.
-2y - 4 = 18y
Move numbers with variables on one side and the constant on the other. Remember to change the signs.
-2y - 18y = 4
-20y = 4
Move -20 to the other side and it would be divided by 4.
y = 4/-20
Simplify the fraction.
y = -1/5
