Question

How do you do the equation 7-4.9t=15 7.6t?

Answer 1

Simplifying
7 + -4.9t = 15 + 7.6t

Solving
7 + -4.9t = 15 + 7.6t

Solving for variable 't'.

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

Add '-7.6t' to each side of the equation.
7 + -4.9t + -7.6t = 15 + 7.6t + -7.6t

Combine like terms: -4.9t + -7.6t = -12.5t
7 + -12.5t = 15 + 7.6t + -7.6t

Combine like terms: 7.6t + -7.6t = 0.0
7 + -12.5t = 15 + 0.0
7 + -12.5t = 15

Add '-7' to each side of the equation.
7 + -7 + -12.5t = 15 + -7

Combine like terms: 7 + -7 = 0
0 + -12.5t = 15 + -7
-12.5t = 15 + -7

Combine like terms: 15 + -7 = 8
-12.5t = 8

Divide each side by '-12.5'.
t = -0.64

Simplifying
t = -0.64
