A variable represents an unknown, numerical value that can vary, taking on different values.
Step-by-step explanation:
In algebra/math, a variable stands for an unknown quantity that can vary, taking on different values. It is often represented by the letter x, but it can be different kinds of symbols such as a, b, z, etc.
Just conver them to mproper fraciton
1 and 1/4=1+1/4=4/4+1/4=5/4
5/8+5/4
make bottom numbers same
8
5/4 times 2/2=10/8
5/8+5/4=5/8+10/8=15/8=8/8+7/8=1 and 7/8
The answer would be B) (5,-2)
I’m also stuck on this question
5 (x - 4) = 3x + 4
5x - 20 = 3x + 4
5x - 3x = 4 + 20
2x = 24
x = 12
