Problem of pre algebra
Introduction
Problem solver pre algebra it is a division of mathematics that substitutes letters for numbers. In this division of mathematics, we use letters like a, b, x and y to denote numbers. The stage of addition, subtraction, multiplication, division or extraction of roots on these symbols and real numbers are performed in problem solver pre algebra, we get what are called algebraic expressions. An algebraic equation solver represents a scale, what is finished on one side of the scale with a number is also completed to the other side of the scale. Practice of the word can be implicit by a simple example 8+2 =8+2 =10 this type of mathematics is called algebra, problem solver pre algebra.
Problem of pre algebra:
Ex:1
solve the equation:
(-3z - 33) - (2z - 22) = -(3z + 33) - 2z + 22
= -3z-33- 2z + 22
=-5z-11
answer is 5z-11
Ex:2
To find algebraic expression
(x -12) + 4y - 3(x -y -2) +6
Sol:
Multiply the factor terms,
= x - 12 + 4y -3x + 3y + 6 + 6
Combine like factor terms, the same terms becomes zero.
= -2x+7y
The final result is -2x+7y
Ex:3
To find algebraic expression
(g -11) + 2g - 5(g -f -2) +100
Sol:
Multiply the factor terms,
= g - 11 + 2g -5g + 5f + 10 + 100
Combine like factor terms, the same terms becomes zero.
=-2g+5f + 99
The final result is 2g+5f + 99
Ex:4
solve the equation:
Sol:
20(-2x - 1) - (x -50) = -20(2x + 1) - x + 50
= -40x-20- x + 50
=-41x+30
So the final result is -41x+30
problem of pre algebra:
Ex:5
The sum of five times a number plus 1000 is 2000, find the number.
Sol:
Sum of five number =5w
So that 5w+ 1000 = 2000
5w = 2000-1000
5w= 1000
w= 200
The final result is w= 200
Line equation for problem solver pre algebra:
Ex:6 To find slope and intercept: y = x-1
Sol:
General equation of slope and intercept, y = mx +b
y = x-1
Rewrite the equation, form of slope and intercept
Y = x-1
Y = x – 1
From the equation slope m = 1
Intercept b = -1
The final solution is m = 1, b= -1.
Prob:1
(-3z - 5) - (2z - 2) = -5z-3 (result)
Prob:2
(-2y - 5) - (2y - 3) = -4y-2 (result)
Prob:3
(-8y - 6) - (2y - 5) = -10y-1 (result)
