You can put this solution on YOUR website! -3(t-5)-2(2t+1)=-8
Multiply -3 by each term inside the parentheses.
(-3t+15)-2(2t+1)=-8
Multiply -2 by each term inside the parentheses.
(-3t+15)+(-4t-2)=-8
Remove the parentheses that are not needed from the expression.
-3t+15-4t-2=-8
Since -3t and -4t are like terms, subtract 4t from -3t to get -7t.
-7t+15-2=-8
Subtract 2 from 15 to get 13.
-7t+13=-8
Since 13 does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting 13 from both sides.
-7t=-13-8
Subtract 8 from -13 to get -21.
-7t=-21
Divide each term in the equation by -7.
-(7t)/(-7)=-(21)/(-7)
Simplify the left-hand side of the equation by canceling the common terms.
t=-(21)/(-7)
Simplify the right-hand side of the equation by simplifying each term.
Answer: t=3
You can put this solution on YOUR website! please help me with this equation. i did the distributive property and i think im doing it right can someone help.
-3*(t-5) = -3t + 15 and
-2*(2t+1) = -4t - 2 so we have:
-3t + 15 - 4t - 2 = -8
Collect like terms:
-7t + 13 = -8
Subtract 13 from both sides:
-7t = -21
Divide bith sides by -7:
t = 3

I assume you're looking for the Value of T, so lets solve.
is is is .
that simplifies to
