Simplifying 2 * n = 5 * 12
 
Multiply 5 * 12 2n = 60
 
Solving 2n = 60
 
Solving for variable 'n'.
 
Move all terms containing n to the left, all other terms to the right.
 
Divide each side by '2'. n = 30

Simplify the expression. 3t(t - 5) + 6t to the 2nd power
Nadusha1986 [10]
<span>: 2s + 3t = 28, 2s = 28 - 3t s = 14 - 3t/2 Substitute s into second equation 5s + 6t = 61, 5(14 - 3t/2) + 6t = 61, 70 - 15t/2 + 6t = 61, 70 - 3t/2 = 61, 3t/2 = 9, t = 6. We can then substitute t back into first equation: 2s + 3t = 28, 2s + 3 * 6 = 28, 2s = 10, s = 5. So the final answer is: s = 5 t = 6</span>
