Find the value of the variable that would make the equation true. 2y + 5y = -28

Sagot :

[tex]2y+5y=-28[/tex]
We combine like terms and get
[tex]7y=-28[/tex]
We divide the equation by the coefficient of the variable y which is 7 to leave y at the left-hand side.
[tex] \frac{7y}{7} = \frac{-28}{7} \\ y=-4[/tex]

Therefore y is equal to -4
2y + 5y= -28
7y =-28
y= -4......just add the same variables..then, divide it both sides to cancel the numer with variable..,,so thts it..bring down
