Answer:
t = (y + 10)/2
Explanation:
Make t the subject in
2(t - 5) = y
Step 1
Expand the bracket by multiplying each term in the bracket by 2
2Xt - 2X5 = 2t - 10
2t - 10 = y
Step 2
To move 10 to the other side of the right hand side (RHS) of the equation, we add 10 to both sides of the equation.
2t - 10 + 10 = y + 10
2t = y + 10
Step 3
Make t the subject by dividing both sides of the equation by its coefficient, 2
2t/2 = (y + 10)/2
t = y+10 / 2
