Answer:
A variable is a letter, for example x, y or z, that represents an unspecified number.
6+x=12
To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12.
If we know the value of our variables, we can replace the variables with their values and then evaluate the expression.
Step-by-step explanation:
6z+4x=?
Solution: Replace x with 3 and z with 2 to evaluate the expression.
6z+4x=?
6⋅2+4⋅3=?
12+12=24

B.4
1/4 divided by 2
do the reciprocal
1/4 times 1/2=2/8
divide 8by 2
-7 + 56x = 105
56x = 105 + 7
56x = 112
x = 2
Think of the greater than sign as an equals sign. Then, you solve for m
