3q = 18 q = 6
3q + 5 + 2q + 5 = 65 5q + 10 = 65 5q = 55 q = 11 Check it. 33 + 5 + 22 + 5 = 65 It checks.
2p + 3q = 13, 5p - 4q = -2 Multiply the first equation by 4 and the second by 3 and add them, which gets rid of the q: 8p + 15p = 52 - 6, and 23p = 46, so p=2. Plug that into the first equation to find q: 4 + 3q = 13, so q=3. Test your answers in the second equation to be sure: 5(2) - 4(3) = 10-12 = -2. It checks. So p=2, q=3.
6p + 11q + 4
It is 2p + 3q. This is an expression and so cannot be solved. It cannot be simplified, and without information about the values of p and q, it cannot be evaluated.
3q = 18 q = 6
It is not an equation if it does not have an equals sign. You could simplify it but not solve it.
q=-6
3
3q+11+8q>99
P = 3a - 3q Add 3q to each side: P + 3q = 3a Double each side: 6a = 2P + 6q
steps to solve 4(3q-q): =(4)(3q+-q) =(4)(3q)+(4)(-q) =12q-4 answer: 8q
3q + 5 + 2q + 5 = 65 5q + 10 = 65 5q = 55 q = 11 Check it. 33 + 5 + 22 + 5 = 65 It checks.
(4p - 1)(3q - 2)
3q + 2z, although it could be 2*(3q+z)
3q+4r-s+5q-6r+2s
we have -3q=5 so dividing both sides of the equation by -3 yields q=-5/3.
