To solve the equation -8x-3y=-1, substitute the value of x from the first equation into the second equation and solve for y. The value of y is 3.
To solve the equation -8x-3y=-1, we can substitute the value of x from the first equation into the second equation. The first equation is given as x = -2y+5. Substitute this value of x into the second equation:
-8(-2y+5)-3y=-1
Expand the brackets and simplify the equation:
16y - 40 - 3y = -1
Combine like terms:
13y - 40 = -1
Add 40 to both sides:
13y = 39
Divide both sides by 13:
y = 3
