2(r-5)=3-(4+t)

Solution for 2(r-5)=3-(4+t) equation:

Simplifying
2(r + -5) = 3 + -1(4 + t)

Reorder the terms:
2(-5 + r) = 3 + -1(4 + t)
(-5 * 2 + r * 2) = 3 + -1(4 + t)
(-10 + 2r) = 3 + -1(4 + t)
-10 + 2r = 3 + (4 * -1 + t * -1)
-10 + 2r = 3 + (-4 + -1t)

Combine like terms: 3 + -4 = -1
-10 + 2r = -1 + -1t

Solving
-10 + 2r = -1 + -1t

Solving for variable 'r'.

Move all terms containing r to the left, all other terms to the right.

Add '10' to each side of the equation.
-10 + 10 + 2r = -1 + 10 + -1t

Combine like terms: -10 + 10 = 0
0 + 2r = -1 + 10 + -1t
2r = -1 + 10 + -1t

Combine like terms: -1 + 10 = 9
2r = 9 + -1t

Divide each side by '2'.
r = 4.5 + -0.5t

Simplifying
r = 4.5 + -0.5t
